import { ttyfast } from "https://deno.land/x/denops_std@v4.2.0/option/vim/mod.ts";
Indicates a fast terminal connection. More characters will be sent to the screen for redrawing, instead of using insert/delete line commands. Improves smoothness of redrawing when there are multiple windows and the terminal does not support a scrolling region. Also enables the extra writing of characters at the end of each screen line for lines that wrap. This helps when using copy/paste with the mouse in an xterm and other terminals.
(default off, on when 'term' is xterm, hpterm, sun-cmd, screen, rxvt, dtterm or iris-ansi; also on when running Vim in a DOS console)
