feature request: enter to confirm keybind

[universalmind303]

most forms allow you to hit ENTER or RET to submit the form

ENTER should be a shortcut for manually clicking button shown below

They're just styled button elements so they should respond to Enter/Space already, but they'll need to have keyboard focus for that, which you can get by hitting Tab (depending on context you might need to press it a couple of times, I think because my GitHub link is rendering above the modal overlay it comes first in the tab indexing...)
