The shortcuts in Geary don't work in combination with control keys. That's an issue since Gnmoe overall uses this forward typing search. And it is pretty annoying by for example losing mails when the 'a' is accidentally hit – by trying to search for something or by mistake. Please make the default setting using control keys (at least for actions, which can be overlooked easily, like archive, delete, etc.).

The current setting could be made active by a settings switch, of course. But I don't recommend this "expert" setting to be the default.
