How can I selected, for instance, 5 lines of code, and replace all instance of myObject1 with myObject2. If subsequent lines of code contain myObject1 reference that I wish not to change... This way I can quickly apply of find & replaces in this scope of code very conveniently without worrying about side effects. Is this possible?
for me it is CTRL + H or CTRL + SHIFT + H
On Windows, and I think Mac, holding alt + left click on a section of code when paused in the debugger will evaluate the expression and show the value in a tooltip. It's much more convenient than alt + f8 and ctrl + alt + 8.
In Linux Mint, holding alt and clicking doesn't do anything (I've disabled Mint's "Special key to move and resize windows").
Is there a way to map it to alt + left click, or a different key combination to evaluate an expression by clicking on it?
Found it mapped to ctrl + alt + shift + left click under Quick Evaluate Expression as a Mouse Shortcut.
Settings -> keymap, change from "Default for XWin" to "Default"
I have an issue with IntelliJ IDEA when selecting a big amount of text, and I cannot find the parameter to set to change that. Here is an example of the situation:
My caret is on line 3
I scroll with the mouse wheel towards line 300
I press ctrl + shift
I press the left button of the mouse
Such an action would result in the text from line 3 to 300 being selected in all common editors (even in MS-Word I think), but not in IntelliJ.
Do you know how to set this right?
Thanks!
Why ctrl+shift? Shift is enough to select those lines in most editors, ctrl is most commonly used to add additional items (for example, two ranges with shift).
Ctrl + Shift + Left Click is "Navigate to Type Declaration" in IDEA. See here.
I often use Ctrl + D to copy one line of the code.
Is there a keyboard shortcut in IDEA where I can put a caret on the method name and pressing the shortcut combination duplicate the whole method? Ctrl + D does not help in such case.
Until IDEA does not get a built-in feature like this, you can use this approach (it's pretty quick):
Put caret on the method name line or anywhere inside the method itself
Ctrl + Minus
Ctrl + D
Ctrl + Plus
Or make a Macro like #CrazyCoder suggested.
You can use first Ctrl + W to select method. Then Ctrl + D to duplicate selected lines.
I know that Ctrl + N is to find classes and it is very useful. But what about methods?
ctrl + F12 (cmd + F12 on macOS) will show all members of the current class in a popup window and let you pick up one. It works exactly like the ctrl + o shortcut in eclipse, much faster than ctrl + alt + shift + n
Windows : ^ ctrl + F12
MacOS : ⌘ cmd + F12
Above commands will show the functions/methods in the current class.
Press ⇧ SHIFT TWO times if you want to search both class and method in the whole project.
Ctrl + Alt + Shift + N allows you to search for symbols, including methods.
The primary advantage of this more complicated keybinding is that is searches in all files, not just the current file as Ctrl + F12 does.
(And as always, for Mac you substitute Cmd for Ctrl for these keybindings.)
Android Studio on Mac
Command + Option + O
Opens up the Symbol lookup that you can jump to most of the methods/functions in your currently opened document.
Intellij IDEA 2017.3.4 - 2018.2 (Ultimate) on OSX
CMD + fn + F12
will show all members of the current class in a popup window, then you can search method in that class.
BUT, this answer is depends on your Keyboard setting. If your keyboard setting in
System Preferences > Keyboard > Use all F1, F2, etc. keys as standard function keys
is selected, then the shortcut becomes
CMD + F12
CTRL + F12 brings up the File Structure navigation menu, which lets you search for members of the currently open file.
IntelliJ IDEA Version 12.13 Ultimate Edition:
Macs:
command + option + shift + N
or on Menu -> Navigate > Symbol ...
Slightly beside the actual question, but nonetheless useful: The Help menu of Intellij has an option 'Default Keymap reference', which opens a PDF with the complete mapping. (Ctrl+F12 is mentioned there)
If you just want to look for methods:
On mac OS X 10.5+ binding, it is Alt + ⌘ + O
By Default XWin Key binding, it is Shift + Ctrl + Alt + N
You can also press double SHIFT then, you can search anything (not only method, but also class, files, and actions)
It is worth adding that if you want to search for a method of a class, you can use a . (dot) between the class and method name inside of either the search everywhere or search symbols dialog. This even works with IDEAs usual search benefits. For example, you can search for LDT.now and LocalDateTime::now will pop up as a result. (As long as you are searching All Files and not just Project Files).
If you click on a method, you can do Ctrl + B to go to that method's declaration. Similar to F12 in MS Visual Studio.
To Find the actions build in the IDEA(reindent, create new, ...) you can use
CRTL+SHIFT+A
then type indent for example and ENTER.
If I need navigate to method in currently opened class, I use this combination: ALT+7 (CMD+7 on Mac) to open structure view, and press two times (first time open, second time focus on view), type name of methods, select on of needed.
Intellij v 13.1.4, OSX
The Open Symbol keyboard shortcut is
command+shift+s
Ctrl + Shift + Alt+ 7 after selecting the method
I tried SHIFT + SHIFT and ALT + CMD + O
But I think the most powerful and easy to use feature is find in all files CMD + SHIFT + F.
Choose regex and write .*partOfMethodName.*\( and it shows all places and can see the actual source code in place without going to that specific file.
