In Microsoft Excel for Mac 2011 (14.0.0) how can I modify the enter/return key to edit in cell instead of moving the selection down? I know that in Preferences > Edit you can uncheck the box that says "After pressing RETURN, move selection [Down/Right/Up/Left]" which at least makes it a little less annoying, but this behaviour is still not productive.
I'm aware I could emulate the effect using Automator, macros, Butler and whatnot but I prefer not to use a third-party application to do this. I'm open to modifying the system preferences and I'm comfortable using the Terminal, though.
EDIT: I found out here http://www.electrictoolbox.com/keyboard-shortcuts-excel-mac/ that CTRL+U is the keyboard shortcut for edit in cell. Now if it were somehow possible to remap that to CMD+Return by editing some plist file or writing some magic formula in the Terminal, it would be perfect!
