Non-recursive remapping

[johnfn]

Our remapping is currently recursive mapping, done in vim with :map. For instance, if you map j to jj, then VSCodeVim will go into an infinite loop and die when you press j.

More generally useful is nonrecursive mapping, done in vim with :noremap. If you nonrecursively map j to jj, then pressing j just acts as if you had pressed j twice instead.

Non-recursive mapping is actually not hard at all to do; I suspect it will be less than 20 lines of code. I only marked it as medium because ya gotta know where those lines of code go.
