Feature Req: Keyboard Navigation (!) for Anbox

[ComedyTomedy]

SimpleTask seems to run well on Linux in Anbox, but with one major problem: There's no way to access the Saved Filter drawer (because I can't swipe).

I have no idea how feasible/easy this is, but it'd be lovely to:

1. Have non-swipe access to Filters
2. If it's by key, also have key shortcuts for some commonly-used actions

Here's a few key suggestions off the top of my head

• [Esc] already exits Quick Filter, Overflow Menu, Selected Tasks, & Add/Update Task, but should also close the Search Bar.
• Ctrl-f could enter search.
• / for Saved Filters, and \ for Quick Filter.
• RET to add task.
• Modifying filters, overflow menu and interacting with tasks are probably fine with the mouse.

No idea how these would be documented; I expect anyone who needs it would google.
