Code quality remained the same when pulling 2a181d1 on baudren:74-Shortcuts into bafe9e5 on baudren:devel.

I added custom Actions for the tabs. I haven't found a way to add custom shortcuts directly to the tabs (what is strange in my opinion).

can I combine the methods setActiveTab... to one method? I would have to use a custom slot @Slot(QtGui.QWidget) and somehow use the widget in the connect-call, right?

EDIT: OK, I found a way by using the sender of the signal

Nice work. What about ctrl+F for new folder in the library tab? And ctrl+T for exterior editor?

[egolus]

Ctrl+F is normally search but ok, I think it's still better than Ctrl+R. Ctrl+T is normally open new tab, but as we don't have a feature like this I like it, too

Edit: aaah, I remember why I didn't use Ctrl+F: As I want to have the underlined character as a shortcut indicator, I tried to have the same shortcut both with Ctrl and Alt. And Alt+F is allready used for the &File-menu

Works nicely, and the tests run fine. Can I merge it?

[egolus]

It still bugs me that we can't test the shortcuts, but yes, I think, I'm finished
