unless you use emacs =/ or screen.... or.. even going to the beginning of a line in shell.
annoying.
at least they exposed the control up arrow binding so you can tell it to stop launching mission control. but no ctrl-a = suck. It's being blocked somewhere high up because it isn't being passed to vm's either.
I use CTRL-A / CTRL-E all the time, for text fields, text boxes and other stuff, in Safari, Firefox, Pages, Terminal, etc, and so on. I realize how often I use it when I use some odd applications like Word when I annoyed that it doesn't work.
It moves to the beginning of the line in anything that supports emacs key bindings (which Cocoa does.)
Anyway. Ctrl-a being probably the key combo that I use most of anything ever, I set out to figure out what was causing this the moment I ran into the problem.
It is indeed being caught somewhere very high up as it just did not register anywhere, except on another computer through Teleport. That was literally the only place it still worked.
You can fix this problem by deleting the following plist file, which will reset all your keyboard shortcuts: com.apple.symbolichotkeys.plist in ~/Library/Preferences, and then logging out and back in again.
I'm sure it's an oversight... on dp3 control up-arrow was linked to mission control with no way to change it (which messed me up in emacs).. in dp4 it's listed in the keybindings so you can change it... but now control a isn't working.
it will be fixed... but it's a showstopper for an old *nix fart like me. I can't even use control a or e inside of virtual machines running in dp4.. annoying
edit: that above fix worked, thank you
edit: this is very odd... the above fix also seems to have fixed safari not scrolling correctly.. this was literally the first thing I did on a fresh install + software update.
