This link points to a page listing unused keys in vim.

This page also lists keys that are synonyms of other keys in terms of functionality, meaning that these keys can be safely remapped.

    This answer would benefit from having at least some of the unused keys listed as part of the answer. If that link were ever to break, this answer would be rendered useless, except to suggest that Yes a list does (or did, if the link dies) exist. For more information, see this Meta post about Link-only answers. – Davy M went to fund Monica Dec 3 at 5:07
  • This answer doesn't mention alt/shift keys. – ideasman42 Dec 4 at 5:24
