Any keyboard commands (except arrows and space) don’t work in scene view in Mac version of Unity. Pressing any button on keyboard gives normal sound for blocked element in OSX. When I go to Unity - Preferences - Keys and try to change layout unity gives me strange index number of key instead of symbol on the button. 
. Is there any way to fix it?
have you tried holing down right click and W/A/S/D I have a mac and it works fine
I changed my system language from Russian to English and now it works fine, but it seems like Unity 4 have issue with Russian (and probably some other non-latin based languages)
