What keyboards are everyone using for these setups? I find by the time you've got three layers (desktop, tmux, vim) the bindings are getting really complicated and inconsistent. Alt-tab might switch applications but then some lower programs use alt for a lot of things.

I'd love something configurable, like a dedicated WM key, a dedicated tmux key and a dedicated vim/app key.

I'm sure it's possible to setup manually, but it would take a lot of work.
