Having worked for years with Eclipse (and some time with Netbeans), I have to admit that using Android Studio (based on InteliJ) I’m fining harder that what it should be. Where’s all my key shortcut combinations!
Whenever I use Netbeans, I use the Eclipse keymappings option in the settings, so I don’t have to remember any new key shortcuts. I’m not sure if Android Studio/IntelliJ has this option as well, but in the meantime, here’s some notes for useful things to remember.
Organize Imports (Eclipse: shift-Ctrl-O) / Optimize Imports: Ctrl-Opt-O
Jump to definition (Eclipse: F3) : Opt-Cmd-B
Fix error with popup suggestion: Opt-Return
