The same goes for (, { and comments ". Also I use alt+shift+t / alt+shift+f to insert ifTrue: / ifFalse: (alt+shift will be probably different on non-linux).
And the most important shortcut of all ctrl+shift+f to reformat code (doesn't work in workspace :'( ).
Also ctrl+alt+r / ctrl+alt+l to indent (move right) / de-indent (move left) selection (unlike code formatting works also in workspace).
Maybe this could be written somewhere centrally along with other shortcuts in other contexts? (do it / browse / switch between windows, open workspace / etc.).
Shortcuts are great but I find them mostly by accident. :(
