[noibruee] Vi-like editor using only letters

Replace the punctuation commands in vi (vim, etc), like / for search, commands using only letters a-z.  The goal is to create an editor that can be used with very small keyboards, for example smartphones including touchscreens.  Perhaps English words as commands, too, as autocorrect has become optimized for typing those.

Replace numbers 0..9 with zabcdefghi (for things like repeat argument).

ESC button is on-screen. Or remap (say) qq to escape in Insert mode (maybe qw inserts literal q, and qu inserts literal qu).  But we don't want Pasting arbitrary text into Insert mode to escape.
