I have a bit of a strange problem! I've been working on FCP7 for ages but finally decided to try and buy FCPX. I've made my own keyboard shortcuts on FCPX as close as I can get to FCP7. However, when I try to assign "Zoom out" command to Up Arrow key it stays there just as long as I don't quit FCPX. When I quit FCPX and reopen it the command is gone and it's back to it's default one (UP). I mean, every other assigned command works just fine but this doesn't. I tried repairing permissions and whatnot but the problem persists. Does anyone have any idea what could that be? Oh yeah, it also happens on my MacBook Pro!
