如何使用 vim 命令字符在其帮助文件中查找说明

我尝试了一些 vim 命令,发现该gh命令将启动一个新的命令模式,它显示--select--在我的屏幕上。就像--visual--命令模式一样,此--select--模式可以选择一些文本。

我想了解更多关于这个命令模式的信息,然后我按下F1在 vi 中显示 vim 帮助文件。

我如何才能gh在此帮助文件中找到该命令?

一般来说,要在 Vim 中查找命令的帮助,请使用命令模式(键入:wq以退出的模式):

:help gh

输入完这些内容后,你可以按Ctrld显示可能补全的列表,

:he gh
gh                               c_<Right>                        -menuheight                      zip-copyright                    match-highlight                  Vimball-copyright
ghc                              i_<Right>                        :belowright                      'cmdwinheight'                   netrw-copyright                  <ScrollWheelRight>
'ghr'                            c_<C-Right>                      'helpheight'                     'nosplitright'                   'nowinfixheight'                 <C-ScrollWheelRight>
g:ghc                            c_<S-Right>                      'splitright'                     'winfixheight'                   shift-left-right                 <S-ScrollWheelRight>

正如您所见,gh已列出,因此只需按Enter

                                                        gh
gh                      Start Select mode, characterwise.  This is like "v",
                        but starts Select mode instead of Visual mode.
                        Mnemonic: "get highlighted".

使用:h select-mode后,您会看到选择模式的描述。以下是摘录:

==============================================================================
8. Select mode                                          *Select* *Select-mode*

Select mode looks like Visual mode, but the commands accepted are quite
different.  This resembles the selection mode in Microsoft Windows.
When the 'showmode' option is set, "-- SELECT --" is shown in the last line.

Entering Select mode:
- Using the mouse to select an area, and 'selectmode' contains "mouse".
  'mouse' must also contain a flag for the current mode.
- Using a non-printable movement command, with the Shift key pressed, and
  'selectmode' contains "key".  For example: <S-Left> and <S-End>.  'keymodel'
  must also contain "startsel".
- Using "v", "V" or CTRL-V command, and 'selectmode' contains "cmd".
- Using "gh", "gH" or "g_CTRL-H" command in Normal mode.
- From Visual mode, press CTRL-G.                       *v_CTRL-G*

...
                                                        *gh*

gh                      Start Select mode, characterwise.  This is like "v",
                        but starts Select mode instead of Visual mode.
                        Mnemonic: "get highlighted".
