IntelliJ IDEA Mac OS X Keymap
Using new software can be frustrating since we are not familiar with the shortcuts etc. I found the keymap of IntelliJ IDEA Mac OS X and listed some useful ones (at least to me) below.
Mac key symbols are confusing to me so I replaced it with the names of the keys.
Command + F1 = Show descriptions of error or warning at caret
Control + option+ | = Auto-indent line(s) ,
Tab / Shift +Tab = Indent/unindent selected lines
Command +W = Close active editor tab
Command +F = Find
Command +G = Find next
Command +Shift+G = Find previous
Command +R = Replace
Compile and Run
Control + R = Run
Shift + F6 = Rename
Command + S = Save all
