feat(ui): add navigation with alt + arrow keys (#1264)

* feat(ui): change from non-working alt-brackets to alt-arrows

* style(fmt): rustfmt

* fix: improve parsing of `alt` combination keys

The binding of the keys can now be specified with:

- Alt: 'c'
- Alt: Up
- Alt: Down
- Alt: Left
- Alt: Right

* chore(fmt): rustfmt
