Hey there! thanks for the issue @benbooth493 , I think it's a good idea and might be a good issue for beginners. Marking as wishlist and good for beginners.

I will give this one a shot, can you assign it to me?

will do right now 👌

Based on Wezterm's leader key configuration, I'm thinking of something like:

[bindings]
leader = { key = "b", with = "control" }
keys = [
  { key = "c", mode = "leader", action = "createtab" },
]

Thoughts?

Looks good, but I think also should allow to configure the timeout on leader key

Good point. I'm kind of stuck at the part where the leader key should activate the BindingMode::LEADER. Can you give me some pointers about how this might work?

FWIW I pushed my WIP changes to https://github.com/orhun/rio/tree/feat/leader-key

@orhun could you open a PR? Gets easier to make comments. I think you are going in the right way but shouldn't make any change on rio-backend/src/crosswords/mod.rs file
