IntelliJ key shortcuts

[makingthematrix]

Ha :)

In my career I usedVisual Studio, Eclipse, IntelliJ on Linux and IntelliJ on Mac OS. As a result, I have remembering key shortcuts for the most popular actions, because apparently designes of each IDE had different ideas, and I suspect that sometimes they just pushed keys at random. The "Cmd/Meta" sign on Macs is also very confusing to me. So, as a part of learning Rust and writing this project I want to finally create and memorize a set of the most important shortcuts I'm going to use them in Intellij in on my projects from now on.

One more problem: Mac OS assigns special character to certain "Left Alt + something" combinations.
Alt+D: ∂
Alt+C: ć
and so on. I had to disable Left Alt from doing anything: https://stackoverflow.com/questions/11876485/how-to-disable-typing-special-characters-when-pressing-option-key-in-mac-os-x

Search for a Class, Create a Class, and Type Info does not work for Rust - only Scala.

Find Action	Cmd+Shift+A	Ctrl+Shift+A	Ctrl+Shift+A
Extend Selection	Alt+Up	Ctrl+W	Alt+X
Navigate -> Class	Cmd+O	Ctrl+Alt+T	Ctrl+Alt+C
Create a new Class	-	-	Ctrl+Alt+Shift+C
Search for a File	Shift+Cmd+O	Ctrl+Alt+R	Ctrl+Alt+F
Create a new File	-	-	Ctrl+Alt+Shift+F
Go to Declaration	Cmd+B	F3	Shift+F3
Quick Definition	Alt+Space		Shift+Space
Find Usages	Alt+F7	Ctrl+G	Ctrl+Alt+U
Find Usages in File	Ctrl+F7	Ctrl+Shift+G	Ctrl+Shift+U

Alright, since I have to use these shortcuts across Linux and Mac, Rust and Scala, and maintain sanity in the process, I decided to create my own shortcuts for the actions which are the most useful to me. Here I'll leave a list of them, together with how they are defined on Mac.

The idea is that I need only 10-15 shortcuts and I can probably assign them to keys which start the name of the action, with Ctrl+Shift, or Alt-Shift as command keys (Ctrl+Alt is usually occupied already by something important).

Ctrl+Shift+A - shows the list of possible actions. It stays like this. Except that, of course, its Cmd+Shift+A on Mac (and I'm going to change it to Ctrl+Shift).

[makingthematrix]

Extend selection: Ctrl+W (Eclipse), Alt+Up (Mac 10.5+). Changing to Alt+X

[makingthematrix]

Search for Class: Ctrl+Alt+T (Eclipse). Changing to Alt+C.
(btw, I added Ctrl+Alt+Shift+C as "Create new Class" for Scala)

[makingthematrix]

Search for File: Ctrl+Alt+R (Eclipse). Changing to Alt+F.
Ctrl+Alt+Shift+F as "Create new File" for Rust.

[makingthematrix]

Go to Definition: F3 (Eclipse). Let it stay like this.

[makingthematrix]

Find Usages: Ctrl+G (Eclipse). Changing to Alt+U.
Find Usages in File: Ctrl+Shift+G (Eclipse). Changing to Ctrl+Shift+U.

[makingthematrix]

Type Info: Alt+Equals (Eclipse). Changing to Alt+I.
In Rust the type is hinted in the editior screen and this shortcut doesn't work... I guess.

[makingthematrix]

Do The Needful: Alt+Enter. Stays.

[makingthematrix]

Basic completion: Ctrl+Space (Eclipse). Stays.

[makingthematrix]

Commenting/uncommenting: Ctrl+Slash (Eclipse). Stays.
Also Ctrl+Shift+Slash which comments the code with a block.

[makingthematrix]

Reformatting code: Ctrl+Alt+L (Eclipse) which interferes with Screen lock on Ubuntu, changing to Alt+L.

[makingthematrix]

Refactor This: Ctrl+Alt+Shift+T (Eclipse) changing to Ctrl+Shift+R.
Worth to remember that Alt+Shift+R (Eclipse) is Rename (stays)
and Alt+R opens the Refactor menu.

[makingthematrix]

Optimize Imports: Shift+Alt+O (Mac), changing to Shift+Ctrl+I

[makingthematrix]

Find in Path: Shift+Cmd+F (Mac), changing to Shift+Ctrl+F
Replace in Path: Shift+Cmd+R (Mac), changing to Shift+Ctrl+R. That removes "Run context configuration".

[makingthematrix]

Navigate Back: Alt-Left (Eclipse). Stays.
Navigate Forward: Alt-Right (Eclipse). Stays.

[makingthematrix]

Move a block of code up: Alt+Up (Eclipse). Changing to Shift+Alt+Up.
Move a block of code down: Alt+Down (Eclipse). Changing to Shift+Alt+Down.
Move a line up: nothing on Eclipse. Changing to Alt+Up.
Move a line down: nothing on Eclise. Changing to Alt+Down.

I find moving lines of code much more useful than moving whole blocks. If I want to move a function or a data structure, I can easily select it with a mouse and I have much more control over it this way. And moving single lines is one of the most common things I do during refactoring.
