How to make vi redraw screen?
提问by Sam Liao
When I use
当我使用
git commit --amend
It will enter into a vi window to let me input comments for commit, the problem is the vi windows will show some dirty characters from former shell background. So I wonder how can I let vi to reload or redraw the screen to make the screen normal.
它会进入一个 vi 窗口让我输入提交的注释，问题是 vi 窗口会显示一些来自前 shell 背景的脏字符。所以我想知道如何让vi重新加载或重绘屏幕以使屏幕正常。

In Vi both of these are redraw:
在 Vi 中，这两个都被重绘：
- ^R ( does not work with VT100 type terminals )
- ^L ( does not work with Televideo terminals )
- ^R（不适用于 VT100 型终端）
- ^L（不适用于电视终端）

As noted in the comments Vim now uses ^R for redo and ^L alone for redraw.
正如评论中所指出的，Vim 现在使用 ^R 进行重做，单独使用 ^L 进行重绘。
