从右到左输入

是否有命令使Vim从右到左键入？如果不是我们任何人都知道这个插件？

当然！

:set rightleft

或者，只是rl。但是，这将按您键入字符的顺序保存文件。如果要使其保存相反，请:%!rev在保存之前键入。

编辑：

如果使用revins或ri选项，则向后插入。您可以将其映射到组合键，但这取决于您。

这是vim帮助的相应部分：

o  Typing backwards                 *ins-reverse*
----------------
In lieu of using full-fledged the 'rightleft' option, one can opt for
reverse insertion.  When the 'revins' (reverse insert) option is set,
inserting happens backwards.  This can be used to type right-to-left
text.  When inserting characters the cursor is not moved and the text
moves rightwards.  A <BS> deletes the character under the cursor.
CTRL-W and CTRL-U also work in the opposite direction.  <BS>, CTRL-W
and CTRL-U do not stop at the start of insert or end of line, no matter
how the 'backspace' option is set.

There is no reverse replace mode (yet).

If the 'showmode' option is set, "-- REVERSE INSERT --" will be shown
in the status line when reverse Insert mode is active.
