IntelliJ Keyboard Shortcuts

IntelliJ is a very fast editor from jetbrains and does remote debugging more than twice as fast as Eclipse. Searching is also slicker than Eclipse. Here are some handy shortcuts for jet-setting across your source code.

Cntrl-N Jump to class
Cntrl-E Scroll through open files
Cntrl-F and F3 Search and repeat last search
Cntrl-F12 Jump through class (fields and methods)

Alt-F7 Find usages (also click "Open in new tab" to get tabbed search)
Alt-left, Alt-right Scroll through panes (Cntrl-E if you want to jump >1 step at a time)
Cntrl-B Jump to DECLARATION
Cntrl-Alt-B Jump to IMPLEMENTATION

Alt-3 go to Find screen

The Cntrl-MouseUp/MouseDown combination can be used to dynamically zoom in/out of the current pane. This is the same key combination in Internet Explorer for the same operation.
