"Insert" key always brings up "Help" even if system is actually sending an "Insert"

[JoshRodd]

On macOS, an extended keyboard has a "Help" key where the "Insert" key typically is on a PC keyboard (above Delete and left of Home). I often choose to remap this key to "Insert", and also remap the numpad 0 and the special key combo like Fn-Enter.

VimR interprets this as still being "Help". I am aware I can use the "i" and "r" keys to go into Insert or toggle between Insert and Replace mode, but I would like to honour the Insert like neovim does on other platforms.

For reference, when using neovim in iTerm2 (with kitty protocol), I usually map Insert (and Fn-Enter) to the ^[[2~ sequence.
