[From]http://askubuntu.com/questions/412046/unable-to-use-intellij-idea-keyboard-shortcuts-on-ubuntu
As a bit of reading taught me that Intellij IDEA is a keyboard-centric IDE. What it means, is that a use can work with it without having to touch the mouse. Also I manage find keymap setting.
For Ubuntu
See how to change keyboard shortcuts?
Here’s a list of tweaks you need to make with default system key bindings so that they won’t interfere with IntelliJ IDEA actions (listed in brackets).
[code] Disable the Shade window action, assigned to Ctrl + Alt + S (Settings dialog)
Change or disable the Lock Screen action, assigned to Ctrl + Alt + L (Reformat code)
Change or disable the Launch terminal action, assigned to Ctrl + Alt + T (Surround with)
Change or disable the Switch to workspace action, assigned to Ctrl + Alt + Arrow Keys (Navigation)
Disable the Move window action, assigned to Alt + F7 (Find usages)
Change or disable the Resize window action, assigned to Alt + F8 (Evaluate expression)Hope this helps!
Note: You can always revert Ubuntu shortcuts back to its default state. Just refer to How can I restore default keyboard shortcuts?, in case if you’re lost.
