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 use |nvim_replace_termcodes()| (typically with escape_csi=true) to replace |keycodes|, then pass the result to nvim_feedkeys(). Example: :let key = nvim_replace_termcodes("", v:true, v:false, v:true) :call nvim_feedkeys(key, 'n', v:true) Parameters: ~ {keys} to be typed {mode} behavior flags, see |feedkeys()| {escape_csi} If true, escape K_SPECIAL/CSI bytes in keys See also: ~ feedkeys() vim_strsave_escape_csi
