I've used AppCode (Intellij C++/ObjC IDE that replaces Xcode) for a while and really gotten used to being able to Ctrl+Click on any identifier to get to its definition/decleration.
Now on a new work place, I'm using CLion for a somewhat larger code base and Ctrl+Click hardly ever works. It only seem to work when the identifier is in the same file.
Is there anything I need to setup for this to work correctly? CLion seem to index the code successfully and doing text searches works fine.
You need to use import project functionality of CLion from File -> Import Project and give ok for CMakeLists.txt file automatic creation. Never mind the file is for CMake, you can build your project with other tools too, but CLion uses it for the dependencies.
Then append in the beginning of that file a line stating:
include_directories(.)
After that go to File -> Settings and there search for Keymap from the left and after that on right, right below the word "keymap" there is a selection element for taking for example Eclipse default keymapping in use and there you have at least (I tested only it) the ctrl + click functionality working like charm!!
kudos about the include_directories(.) goes to this question: CLion indexer does not resolve some includes in the project directory
You need to press ctrl + alt + shift + n.
And after pressing it a dialog box will appear to enter your variable/function name and click enter.
Tip: Filter the result for a better experience. Filter option is present on right side of the dialog box.
To get a quick peek of function/variable definition press ctrl + q while focusing on the variable or function.
To get the detailed or full definition of function press ctrl + shift + i while focusing on the variable or function.
I just looked at one of my more complicated teaching examples with multiple header/source files where this would come up.
What I see is that ctl-click (and the red/green arrows in the gutter) does work only in the same file. But I can right-click on a method from another file and choose to go to either the declaration (in header) or definition (in cpp).
The hotkeys to do this are not ctl-click. But you can remap hotkeys in IntelliJ ides, so you may be able to come up with hotkey combinations that don't seem too awkward to you.
What helped me was to run File > New CMake Project from Sources
Until that point, Ctrl+click in CLion would go to the definitions, but wouldn't find any usages.
IntelliJ IDEA automatically shows a red line if it cannot resolve some entities or it detects an error. Is there a way to copy and paste the content of that tooltip?
With eclipse I use the f2 to get the information.
I used the idea version 14.1.4 and use this way to copy the tooltips.
You can click the error line and the info will display, now you can right click to copy this error info.
Mouse shortcut:
Hover mouse over error in editor to bring up tooltip
Alt + click on error message inside tooltip to copy it to clipboard
For step 1 you can also bring up the tooltip for the current carret position by Ctrl + F1. For step 2 there does not seem to exist a keyboard shortcut at the time of writing (for IntelliJ 2018.1), see also IDEA-65636.
If you stumbled upon looking for solution for Linux version (and none of the above worked for you, like for me) click ctrl+alt+left mouse button on the tooltip, and you'll get its content into the clipboard :)
No, the tooltips don't offer a way to get that information from their context alone.
You could traditionally compile it instead via Build -> Compile and get the error message that way, instead. You can then select this text and do with it what you wish.
There is a bug report on this since 2011 (!) . Feel free /encouraged to vote for having the bug fixed:
https://youtrack.jetbrains.com/issue/IDEA-65636
IDEA-65636 I can't copy text from tooltip, though I can select it
Though honestly JetBrains infrequently gets around to non super critical bug fixes.
Is there a command to navigate to a next problem in a whole project but in a file. It happens all the time that you have an error somewhere and you need to trace your project in a Project View to find it.
How cool would it be to navigate where you need just right away!
Update:
Not only compilation errors count, but also syntax.
You can use "Analyze"->"Inspect Code". It will shows all issues in the whole project.
CTRL + F9 (Make Project). This will also automatically scroll to your first error in the project. It will give you a list of your errors and you can then use CTRL + ALT + DOWN to go through the errors.
Also once you fix them, you can do the shortcut again as it might reveal more (compilation) issues that were hidden by the first ones.
IntelliJ IDEA has an inspection that checks for spelling. In the analysis overview, I can see how many spelling mistakes were found, e.g. 12 typos found. In the code they are highlighted using a wavy green line.
However, I find it very hard to look manually for those wavy lines. Is there a keyboard shortcut or a search function which will automatically skip to the next highlighted typo?
F2 and Shift + F2 shortcuts will navigate you to the Next / Previous highlighted error. You need to configure the error navigation first to Go to next problem instead of default Go to high priority problems option(from the context menu of editor right side bar):
See help for details. Another option is to use double click (F4 shortcut) from the Inspection Results window to go to the source.
IntelliJ IDEA 2016.3
If you want to fix all typos from the project, you can list all of them and iterate through them using double click (or F4 to open the source):
Analyze > Run Inspection by Name...
Type "Typo"
You will be able to see a list containing all typos grouped by file:
In Settings -> Editor -> Colors & Fonts -> General, you can add an 'Error stripe mark' color to Typo.
With the default settings of IntelliJ I find it difficult to spot the typos. So I do the following hack to spot and correct them once in a while.
Temporarily change inspection setting to show Typos as Errors.
IntelliJ then highlights the typos as Errors, making it much easier to spot them in the editor. I correct them and then revert the inspection setting changes. The changes can be kept permanently but I don't prefer that!

Locked. This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions.
I did a bit of googling hoping to find a post on IDEA shortcuts similar to Jeff's post on Visual Studio shortcuts (Visual Studio .NET 2003 and 2005 Keyboard Shortcuts), but didn't really spot anything that helped. Hopefully the answers to this question will fill the void.
These are some of my most used keyboard short cuts
Syntax aware selection in the editor selects a word at the caret and then selects expanding areas of the source code. For example, it may select a method name, then the expression that calls this method, then the whole statement, then the containing block, etc.:
Ctrl+W
Basic Code Completion, to complete methods, keywords etc.:
Ctrl+Space
Go to Declaration. Use this to navigate to the declaration of a class, method or variable used somewhere in the code:
Ctrl+B
Introduce Variable Refactoring, to create a variable from an expression. This expression may even be incomplete or contain errors. Since version 8, IDEA intelligently selects a likely expression when no text is selected:
Ctrl+Alt+V
Go to Class, to quickly open any class in the editor:
Ctrl+N
To open any file, not just classes:
Ctrl+Shift+N
Comment/Uncomment current line or selection:
Ctrl+/ and Ctrl+Shift+/
Quick JavaDoc Popup to show the JavaDoc of the method or class at the text cursor:
Ctrl+Q (Ctrl+J on Mac OS X)
Smart Type Completion to complete an expression with a method call or variable with a type suitable in the current Context:
Ctrl+Shift+Space
Rename refactoring to rename any identifier. Can look in comments, text files and across different languages too:
Shift+F6
Select in Popup to quickly select the currently edited element (class, file, method or field) in any view (Project View, Structure View or other):
Alt+F1
Highlight Usages in File. Position the text cursor on any identifier without selecting any text and it will show all places in the file where that variable, method etc. is used. Use it on a throws, try or catch keyword to show all places where the exception is thrown. Use it on the implements keyword to highlight the methods of the implemented interface:
Ctrl+Shift+F7
By far my favourite all purpose shortcut is Ctrl+Shift+A
It does a search as you type through all the commands in intellij. Not only that but when you find the command you want it also displays the corresponding shortcut key next to it!
Here are the Intellij IDEA keyboard shortcuts I find most useful (listed in roughly the order of usage for me):
The shortcut I use the most is Ctrl + B (Go to declaration), to see what a method does, where a variable is declared etc. This is almost always followed by Ctrl + Alt + Left to get back to where I was (Ctrl + Alt + Right works to “go forward” again).
A related navigation shortcut is Ctrl + Alt + B, (Go to implementation). Press it when the caret is at the method name of an interface, and you get a pop-up list of all the places where this method is implemented, and you can select which one you want to go to (if there is only one implementation, you go straight there). The same goes for overridden methods.
The opposite of this is Ctrl + U (Go to super-method/super-class). If the caret is at the implementation of a method in an interface (indicated by the little green interface-symbol in the left gutter), this shortcut takes you to the interface itself.
When I want to see all the places where a method or variable is used (which I want to do a lot), I use Ctrl + Alt + F7 (Show usages). This gives you a pop-up list of all the usages, and you can easily navigate to each one. I prefer this over Alt + F7 (Find usages), which gives you the same information, but in a separate pane below.
To find classes, I use Ctrl + N (Go to class), which lets you search using only the capital letters in the class name (“camel humps”), and * as wildcard.
Yet another shortcut I use, both when reading and writing code, is Ctrl + P (Parameter info) at the arguments of methods and constructors, to see the types and names of the parameters.
When it comes to writing code, I use Ctrl + space (Basic code completion) a lot to auto-complete method names, variable names etc (or simply to see which methods are available for a certain object, by trying to auto-complete directly at the dot following the name of the object).
For searching in the current file I use Ctrl-F (Find - probably the least surprising shortcut in this list), F3/Shift + F3 (Find next/previous) to repeat the search, and Ctrl + Shift + F (Find in path) to search in the whole project.
Ctrl + W (Select successively increasing code blocks) is handy when selecting chunks of code. Repeatedly pressing it selects more and more of the code. Useful when searching, indenting, commenting out code etc.
If there are errors in the file, F2/Shift + F2 (Next/previous highlighted error) will jump to them.
I use the sequence Alt + C, N (Show Changes View) to see which files in the project I have modified compared to the subversion repository. To diff the current file against the version in the subversion repository, I use the sequence Alt + C, S, Y (Compare with the Same Repository Version). In the diff view, I use F7/Shift + F7 to navigate between the changes.
When not in the diff view, I use Ctrl + Shift + Alt + Up/Ctrl + Shift + Alt + Down to jump to the parts of the file that have been changed compared to the checked-out version. At each modification point, you see the corresponding part in the checked-out version in a pop-up window.
Finally, I run JUnit tests using Ctrl + Shift + F10.
Edit: One really useful shortcut that I've only started using in the last few months is Ctrl + E. It brings up a pop-up with the 15 most recently used files, and you just arrow down to the one you want and hit enter to navigate to it.
According to the Jetbrains folks, it will have to be these, as they are for the one wearing the shirt: (Got that from Devoxx)
Help\Productivity Guide
It tells you what are the shortcuts you use/don't use and displays usage statistics. It will guide you to the unknown features.
Some of the time savers:
Alt + Enter : show intention actions (like Eclipse quick fix)
Ctrl + Alt + V : introduce variable (never type the left hand side of an assignment again)
Ctrl + Shift + Space : smart completion ( even two levels down since IntelliJ 8 )
Ctrl + W : select succesively increasing code blocks. Kind of obvious but a real time saver!
The Canoo blog contains some (+8) articles on some more advanced IntelliJ keyboard shortcuts.
The Key Promoter and Shortcut keys list plugins are really helpful for (constantly) learning new IntelliJ keyboard shortcuts.
Try using the Key Promoter plugin. That will help in learning the shortcuts.
Couple of shortcuts apart from the above suggestions:
Alt + Ins: Works consistently to insert anything. (Add a new class, method etc)
Ctrl + Alt + T: Surround code block. Another useful stuff.
This is probably dependent on your development environment, but when doing BlackBerry development I code in IntelliJ and still compile and debug through the BlackBerry JDE. Ctrl + Shift + C is vital in this case as it allows you to copy the full path of the file you are currently editing, making it easy to open the file in the separate dev environment.
Yes, Ctrl + Shift + A is the most useful one. It's a meta shortcut
Within the tool:
"Help -> Default Keymap Reference"
(as suggested by krosenvold)
On the Internet: "IntelliJ IDEA Developers Documentation"
Windows, Linux and Mac keyboard shortcut reference cards for versions 8, 7, 6, 5, and 4.5.
(I knew I had seen and used these reference "cards" before! ;-)
One of my favorites (not shown on the JetBrains cards) is "Ctrl+Shift+{Up or Down Arrow}" to move lines/methods up and down in the source code.
See also "Intellij Idea Keyboard Shortcuts" page on Ward's Wiki.
Shift+Delete deletes the entire line (will 'cut' it to clipboard)
Ctrl+Alt+L to reformat and optimize imports
Ctrl+Shift+J to join lines (pull content of next line up to current line).
Alt + Shift + Insert - switches to column selection mode, allowing the selection of rectangular text fragments (columns)
Ctrl + Shift + Backspace - go to most recent code edit. Hit again to go even further back. Very useful when coding something, browsing other classes for a while and then wanting to go back where we left our code.
Ctrl+E - recently opened files
Ctrl+Shift+E - recently edited files
Ctrl+Shift+V - paste one of the previous values from clipboard
One of my real favorites may not count as a keyboard shortcut exactly. But the "iter" smart template is really great.
basically if you want to iterate though something using a for loop type "iter" then tab to use the live template
itertab
it will figure out the most likely variable you want to iterate over and generate a for loop for it. I'm pretty sure it uses the nearest reference to an object which supports iteration.
Ctrl + F11 invokes a dialog with all alphanumeric keys on the keyboard. Selecting one empty will add the current line to bookmarks and mark the line with selected key.
Shift + F11 invokes a list of bookmarks. Pressing a key takes to associated bookmark.
Ctrl + Shift + Enter - automatically completes the code statement you are typing, inserting the quotation marks, brackets, curly braces and other punctuation as necessary.
F7 F8 F9 for debugging
If you are coming from Eclipse:
http://tanu.wordpress.com/2010/09/24/moving-from-eclipse-to-intellij-idea/
General documentation and shortcuts are on Intellij's site
http://www.jetbrains.com/idea/documentation/index.jsp
Any combination of Ctrl + Alt + Shift and N.
Ctrl + Shift + T in idea8 is also excellent.
There is a complete keymap in the online help too.
Ctrl + N : Open class.
Alt + F7 : Find usages.
http://www.jetbrains.com/idea/docs/ReferenceCard70_mac.pdf has everything you need. after a while, you'll develop your own preference for certain shortcuts.
This link has everything you need. Plus in Idea 8 atleast, every shortcut is completely customizable, so it's really up to you what the most useful ones are.
