After update to 2015.3, a lot of shortcuts like zoom in/out, fit to canvas, trim to out, etc are not working I thought was the machine, but I just made a fresh install (macpro late 2013 OSX 10.11.6). So after check every faq on the web (even the wacom driver problem for some users) I checked the after effect preferences where the .txt shortcuts is. and its changed. So I dont know If its an error of the programmers in this update or if they actually intended to. if its the second option I thought its a mistake without taking in consideration people that use these tool to live, What I can do i 5 min now takes longer.
