Sounds good. Thanks for working on this.

I hope you'll consider adding help buttons for key descriptions,
as is done in my function `help-substitute-command-keys' (in
`help-fns+.el), which I think you've seen.  Doc:

 (help-substitute-command-keys STRING &optional ADD-HELP-BUTTONS)

 Same as `substitute-command-keys', but optionally adds buttons for help.
 Non-nil optional arg ADD-HELP-BUTTONS does that, adding buttons to key
 descriptions, which link to the key's command help.
