import { allowrevins } from "https://deno.land/x/denops_std@v3.9.2/option/mod.ts";
{only available when compiled with the |+rightleft| feature} Allow CTRL-_ in Insert and Command-line mode. This is default off, to avoid that users that accidentally type CTRL-_ instead of SHIFT-_ get into reverse Insert mode, and don't know how to get out. See 'revins'. NOTE: This option is reset when 'compatible' is set.
