Range select with more than just up/down arrows

[socketbox]

Is your feature request related to a problem? Please describe.
I can't seem to select a range of text in the Unstaged Changes box without selecting one line at a time by pressing or holding down the up/down arrows. This is very slow and tedious.

Describe the solution you'd like
Ideally, I'd be able to select text using vim-like shortcuts, but I understand that the shortcut space is already quite crowded. But it would be super cool to be able to hit v and then have lazygit change keymaps and support all of the standard vim-like shortcuts (ctrl-d /ctrl-u, gg/G, etc). But, short of that, hitting v to toggle range selection and then using either </> or ,/. to select a range would be sufficient.

I'm skeptical about vim-like shortcuts, for reasons that have been discussed here a few times (I'm too lazy to dig up references, sorry). But using </> and ,/. should totally work in range mode, and I'd call it a bug that they don't. Actually, they do in list views (e.g. in the commits panel), just not in the staging view.
