I'm really impressed with the autocomplete feature of the IntelliJ IDE so far.
What I'd like to do, is cycle through the autocomplete suggestions I get when hitting Ctrl + Space without using the arrow keys (↑, ↓).
The reason for this is that I prefer to keep my fingers on the home row (I'm using IntelliJ's Vim emulator additionally).
For example, how would I select sortThis instead of sorted without using the arrow keys or the mouse?
Peter Gromov's answer brought me to a satisfying solution:
In IntelliJ's settings, for Keymap → Editor Actions → Down I set a custom shortcut: Ctrl + J.
This way I can cycle forward through the suggestions.
Setting a shortcut for Down with Selection or Scroll Line Down in the IdeaVim-specific shortcuts did not affect the selection of autocomplete suggestions though.
The answer here: https://stackoverflow.com/a/9713306/2370679 led me to discover that Ctrl+n & Ctrl+p allow navigation of the auto-complete options without having to modify any settings
For macOS the IDE will give a hint that "^↑ and ^↓ will move caret up and down in the editor". These clearly do not work.
There are a few extra steps that are needed after following #matthias-braun's solution.
Here is the full list of step that I use:
Go to Preferences -> Keymap
Expand Editor Actions (not Plug-ins -> IdeaVim)
Select Down
Click the pencil icon or right-click
Select Add Keyboard Shortcut
Press the shortcut (I use ^N)*
Repeat for 3-6 for Up (I use ^P)
Click Ok**
Go to Preferences -> Other Settings -> Vim Emulation
In the drop-down under the Handler column for the row containing Down, select Vim***
Do the same thing for Up
* If you are warned about the key binding already existing then remove it. You can always reset back to the defaults by clicking the little cog icon up the very top to the right of the drop-down menu.
** The Vim Emulation doesn't seem to be populated correctly until you reopen the Preferences.
*** I'm not sure why the Handler should be Vim. This seems backwards to me but it works.
If you're able to scroll up/down in editor with some IdeaVIM-specific shortcuts, they should also work in the completion list.
In this particular case, I'd just type another "t" so that "sortThis" becomes selected (and the only) variant.
I have done the same thing with mapping the arrows but in a more logical way:
I mapped them that when I press 'Alt' 'J' is left, 'L' is right, 'I' is up, and 'k' is down. that way I can have easy access to the arrows while my fingers are on the home row and I don't need to move them nearly as much...
I'm posting it just so people who search it on google can have that idea.

I am an aspiring keyboard user, using IntelliJ to do selective commits to my project.
To do this, I open the Commit dialog with Ctrl+K.
I then press Shift+Tab to switch to the file list, Home to select the root-level node, and Space to uncheck/de-select all files.
I then press the down arrow once or more to select a file, press Ctrl+D to display its diff. I press F7 to go to the first change in the file.
At this point, to the left of the right pane (with the new version of the file) is a checkbox. Not the one at the top which selects all the changes in the file, but the one which selects just the change displayed.
My question is: How do I select/un-select this checkbox without using the mouse cursor? I need to use the mouse as little as possible due to RSI.
Note: When asking questions like this, I sometimes get responses with other pointing device suggestions. Unless you're going to recommend a keyboard technique, I am not interested in your suggestion, and will flag/report your response if that's what it is.
By default there is no keyboard keymap for this action. But you can easily choose new keymap for this.
Go to File->Settings and search for "include" in the search box. What you need is to assign a keymap for "Include Lines Into Commit". Double click on this option and assign any keymap that you want. It is hard to find new keymap that didn't assign to any other action, but only for the demo I choosed Ctrl+T.
You can see what I did in the following image:
Click on Apply and then you can use the keymap that you choose to check/uncheck any individual change checkbox in Intellij commit diff dialog.
In IntelliJ, there are some underlined numbers on the side menus :
1: Project
7: Structure
Like below :
So there is probably a keyboard shortcut which allows to navigate from one view to another by just entering the view number.
I tried the different digits with Ctrl, Ctrl+Shift, Ctrl+Alt etc but could not find the right shortcut.
How can I easily navigate between those views?
The shortcut is Alt + [number]
ps. There's a plugin force-shortcuts if you wanna replace your mouse click actions with shortcuts (https://github.com/treytrahin/force-shortcuts-intellij-plugin). It's super annoying but you learn really fast. And by the way here are such plugins to most editors and IDEs.
ALT+F1 opens a window where you can choose one of the views by pressing the corresponding number.
Info: It actually opens the selected file in the selected view - which is not that bad maybe - but not 100% what you want?
Also there are cool things like pressing C to open a file chosen in Project Explorer directly in Explorer for example.
I like VIM a lot because it kind of doubles the power of my keyboard in a way. It's either in insert or motion or whatever they call it mode.
Navigating through source code, typing code, while being able to keep my hands in the touch type position is great.
But when a dialog box is opened (eg. the one using ctrl+F12), if I have to select something other than the first one in the list, I am forced to have to move my right hand to the cursor keys.
Is there a way so that I can use J and K or else something with ctrl or alt or something, so that I can select an item while keeping my hands in the touch typing position?
You can redefine shortcuts for the Up, Down, Left, Right actions in File | Settings | Keymap (the regular keymap that has nothing to do with IdeaVim). IdeaVim provides Vim emulation only for code editors like file editors, interactive language consoles, etc.
Edit: I guess you can't use j and k since characters typed in the structure window are reserved for searching. But you can use Ctrl+N and Ctrl+P which is the same as the navigation shortcuts for pop-up windows in Vim.
Edit 2: You can't use Ctrl+N and Ctrl+P as well due to this bug in IntelliJ.
Is it possible to change the quick access shortcut numbers for a tool window?
i.e. the numbers next to a tool window name, used by the keyboard shortcut to toggle the window, talked about here
Yep. They are listed in Keymap. MainMenu -> View -> ToolWindows.
P.S.: Idea has a nice Find by shortcut function in Keymap settings page, I used it, to answer your question.
In Android Studio, you can change the Keymap this way:
Preferences -> Keymap
Then open Tool Windows. You may need to scroll down to see all the options.
Right-click on the element you want to assign a new key-stroke. Select Add Keyboard Shortcut. Make sure that the rectangle with a plus in it is selected (use your mouse) and press the key-stroke that you want for this item.
Android Studio will warn you if that key-stroke is already assigned. Click OK to reassign that key-stroke to the item. It'll warn you one more time that you will need to remove the previous assignment for that key-stroke. Click Remove to proceed. You should see the updated keystroke in the right-most column.
What is the quickest way to jump to a particular symbol/selector/class in Xcode? (I'm looking for keyboard shortcuts preferably).
Right now, I know two ways of doing this:
“Open Quickly” > Click on the Symbols dropdown menu at the top of the editor > Select the selector to jump to it.
Click on “Project Symbols” in the “Groups and Files” section on the left sidebar, and type in a name in the Search text field in the top right of the XCode window.
Is there a quicker way of doing this? (If I could even assign a shortcut to jump to the “Project Symbols”, that would suffice for me. Alternatively, if I can find a keyboard shortcut to jump to the symbol dropdown above an editor that would do it to).
For experienced Xcode programmers, what do you use to jump to a symbol?
In Xcode 3.2, the "Open Quickly" command (Shift-Control-D) lets you type in selectors and class names as well as file names. This would at least get you close to what you wanted.
Your idea about using the "Symbols" drop-down also works. You can use the keystroke Control-2 to bring up the Symbols drop-down menu, and then use the arrow keys, or start typing the name of the method that you want to reach.
Edit: In Xcode 4, the "Symbols" drop-down appears when pressing Control-6. You can change this in the Xcode settings by changing the key binding for "Standart Editor > Show Document Items".
If you're looking at the symbol in a source file and want to jump to its definition, ⌘-click it.
(command + double click) on your symbol/selector/class in any place of your implementation to jump to them
(option + double click) on framework classes/selectors to jump to their reference in help->documentation
One (arguably crude) way to do it seems to be as follows:
This is based on the fact that the Search field at the top right of the Xcode window seems to change behavior depending on what is selected in the Groups & Files sidebar.
Select “Project Symbols” in the “Groups & Files” sidebar
Press ⌥⌘F (That is Command+Option+F) to jump to the Search field
Enter the symbol to jump to, and an outline will quickly show up
(this will remain in effect until you click on something else in the Groups & Files sidebar)
