Issue

How do we map or bind keys to control or escape sequences in Hyper?
The config file ".hyper.js", has the keymaps section:

keymaps :{
    "editor:copy": "cmd+c",
    "editor:paste": "cmd+v"
}

But what if I want to map CMD+ALT+UP to a control or escape sequence?
I tried this but it didn't work:

keymaps :{
    "\x1b[1;11A": "cmd+alt+up",
    "\x1b[1;11B": "cmd+alt+down",
    "\x1b[1;11C": "cmd+alt+right",
    "\x1b[1;11D": "cmd+alt+left"
}

Thank you in advance.

Start with the keymaps section in .hyper.js and the attempted escape sequences shown in the issue. Determine how Hyper accepts key bindings for control or escape sequences, then verify the documented mapping with the requested Cmd+Alt+arrow combinations in Hyper.
