What are the most useful Intellij IDEA keyboard shortcuts? [closed]

Answer 1

Some of the time savers:

1. Alt + Enter : show intention actions (like Eclipse quick fix)
2. Ctrl + Alt + V : introduce variable (never type the left hand side of an assignment again)
3. Ctrl + Shift + Space : smart completion ( even two levels down since IntelliJ 8 )
4. 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.

According to the Jetbrains folks, it will have to be these, as they are for the one wearing the shirt: (Got that from Devoxx)

Answer 4

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.

Answer 6

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
