Access shortcuts for alphabetical grouping
To make full use of the new alphabetical grouping a way to directly jump to a group is needed IMHO. I have two possible implementations in mind:
1. If the collection pane is focussed, entering a character would jump to the group matching, if any.
2. Global hotkeys like [Ctrl]+
An advantage of the former would be that it does not clutter the global namespace of possible hotkeys, so those could be used for something else later. Contrary to this would the second implementation not require having to focus the collection pane. This would be rather convenient
This ticket was migrated from the old trac: re #583
