A Grammar for Vim's Normal Mode

A rough attempt at characterizing Vim's Normal Mode grammar that I made while writing this Vim series. See the bibliography there for more context.

Notation: | means or, [] means optional, * means zero or more, <> means literal class (e.g. <number> could expand to 1, 2, etc.), ... means there are more instances not enumerated here (these would need to be fleshed out to get a complete grammar).

It could be interesting to use a grammar like this one to organize an interactive Vim cheatsheet.

normal-command = motion-form

| verb-phrase
