[OS X Emacs] Resize frame keys in Aquamacs 1.4

[Emil Marceta]

Hi there,

Looks like Ctrl+Meta+{Dn, Up, Left, Right} (resize frame) in Aquamacs
has changed;
Left, Right default to text navigation now while Up and Dn keys are unchanged.

Could someone help with restoring the Left, Right keys so they resize
the frame as in 1.3?

Thanks,
emil
