Context menu has underlined access keys assigned.

[Zweibach]

Currently the menu bar has underlined letters (purely cosmetic), in most other programs you would be able to hit that button and open the corresponding menu. Then further options would have a key assigned that you could hit to open the next part. This would allow fairly smooth keyboard navigation of parts of Hydrus.

You mean like, _f_ile, _p_ages, _d_atabase, etc.? You can open those by pressing alt + [letter]. That's pretty standard for this sort of UI. It is true that many other menus could also be making use of access keys that currently do not. I would like to have them in context menus in particular.
