Sends input-keys to Nvim, subject to various quirks controlled by mode flags. This is a blocking call, unlike nvim_input().

On execution error: does not fail, but updates v:errmsg.

To input sequences like <C-o> use nvim_replace_termcodes() (typically with escape_ks=false) to replace keycodes, then pass the result to nvim_feedkeys().

Example:

:let key = nvim_replace_termcodes("<C-o>", v:true, v:false, v:true)
:call nvim_feedkeys(key, 'n', v:false)

Parameters: {keys} to be typed {mode} behavior flags, see feedkeys() {escape_ks} If true, escape K_SPECIAL bytes in keys This should be false if you already used nvim_replace_termcodes(), and true otherwise.
