What's fixed is that your command-o accelerator works in gtk-2.20 and later, as do the standard bindings in gtk/gtkrc.key.mac. This worked in 2.18, but was broken in master last December

There's a problem with mnemonics, which is that by default they use <Alt> with the underlined letter. On a mac, that key combination is used to extend the keyboard to produce additional letters (which ones of course depends on the active key map).  The gdk keymapping code eats <Alt> and returns the extended letter (<Alt>o returns ø). I'm currently working on that, so your letter is timely: I hadn't considered mnemonics.

I think that they're going to have to use <control> instead of <alt>, though. Otherwise someone is going to want to have
(e.g.) _ø for a mnemonic, and there's no way to get there with <alt>.

BTW, there's no support for mnemonics in menus on OSX. explains keyboard menu navigation for Tiger and Leopard (Snow Leopard is the same as Leopard).
