OS X keyboard shortcuts in WYSIWYG editor

OS X keyboard shortcuts used to work fine in WP 2.6 – Alt-B for bold and so on.

With 2.7, the shortcuts don’t work. Also, Apple-(number) does formatting now, which is annoying, because I need those keys for changing tabs in Firefox.

This used to work well in WP 2.6, but is a definite step backwards in WP 2.7.
