vim 使箭头键像大多数普通程序一样工作

Question

我最近发现了 VIM 并开始使用它。我发现箭头和退格键有缺陷。 所以我对退格键做了这个

set backspace+=indent,eol,start

如何对箭头键执行此操作以允许正常导航？

你没有确切地说出你认为箭头键的哪个方面是“有缺陷的”，所以我只能猜测。

您可以使用whichwrap 设置来获得您可能想要的部分内容。来自:help whichwrap：

'whichwrap' 'ww'    string  (Vim default: "b,s", Vi default: "")
            global
            {not in Vi}
    Allow specified keys that move the cursor left/right to move to the
    previous/next line when the cursor is on the first/last character in
    the line.  Concatenate characters to allow this for these keys:
        char   key    mode  ~
         b    <BS>   Normal and Visual
         s    <Space>    Normal and Visual
         h    "h"    Normal and Visual (not recommended)
         l    "l"    Normal and Visual (not recommended)
         <    <Left>     Normal and Visual
         >    <Right>    Normal and Visual
         ~    "~"    Normal
         [    <Left>     Insert and Replace
         ]    <Right>    Insert and Replace
    For example: >
        :set ww=<,>,[,]
    allows wrap only when cursor keys are used.
    When the movement keys are used in combination with a delete or change
    operator, the <EOL> also counts for a character.  This makes "3h"
    different from "3dh" when the cursor crosses the end of a line.  This
    is also true for "x" and "X", because they do the same as "dl" and
    "dh".  If you use this, you may also want to use the mapping
    ":map <BS> X" to make backspace delete the character in front of the
    cursor.
    When 'l' is included and it is used after an operator at the end of a
    line then it will not move to the next line.  This makes "dl", "cl",
    "yl" etc. work normally.
    NOTE: This option is set to the Vi default value when 'compatible' is
    set and to the Vim default value when 'compatible' is reset.

在你的情况下，你可能想要：

:set whichwrap+=<,>

这将使左右环绕行尾。

如果逻辑行和显示行之间的区别让您感到困惑，您还可以尝试在正常和可视模式下将<Up> 和<Down> 映射到gk 和gj。或者，您可以:set nowrap 完全消除这种区别。
