- Editing mode on pty pane should behave the same as if it was a regular text file. You should implement tests that will send the same commands to the same text buffer, but one is a pty and one is a file pane and the result after chaning should be the same. Right now I can't create new lines freely nor split current lines; this might require some refactoring because the pty editing was done in a real simple way.
- Add builtins (that work with 0 args by default) that are reachable via SPC, so like SPC+? will open the Help builtin that will list all bultins that start with the prefix command after SPC and before ?; SPC+h+t will trigger the tutor builtin, SPC+d will be the Del, SPC+k will be the kill (the only new one for now will be the Help builtin)
