VIM 将当前行作为 VIM 命令执行

Question

是否可以在由 VIM 打开的文本文件中执行 VIM 命令？例如，我们可以有以下文本，我们想在不键入它的情况下执行 :help w。

  Read the text in the help window to find out how the help works.
  Type  CTRL-W CTRL-W   to jump from one window to another.
  Type    :q <ENTER>    to close the help window.

  You can find help on just about any subject, by giving an argument to the
  ":help" command.  Try these (don't forget pressing <ENTER>):

    :help w
    :help c_CTRL-D
    :help insert-index
    :help user-manual

Answer 1

您可以创建以下映射来执行当前行中定义的命令:

nnoremap <c-e> :exe getline('.')<cr>

将光标置于 :help w 行并键入 Ctrl+E 将打开帮助页面。
