其他有用的寄存器:

“*”或“+ -”系统剪贴板的内容

/ -最后一次搜索命令

:—最后一个命令行命令。

注意，对于vim宏，您可以编辑它们，因为它们只是记录宏时使用的击键列表。因此，您可以将宏写入文本文件(使用“ap”来编写宏a)并编辑它们，并使用“ay$”将它们加载到寄存器中。存储有用宏的好方法。

一个很大的混淆来源是默认寄存器”。了解它的工作方式是很重要的。如果在大多数情况下避免使用默认寄存器，情况会好得多。来自Vim文档的解释:

Vim fills this register with text deleted with the "d", "c", "s", "x" commands
or copied with the yank "y" command, regardless of whether or not a specific
register was used (e.g.  "xdd).  This is like the unnamed register is pointing
to the last used register.

所以默认寄存器实际上是指向最后使用的寄存器的指针。当你删除或拉取某个东西时，这个寄存器将指向其他寄存器。您可以通过检查寄存器来验证这一点。总有另一个寄存器与默认寄存器完全相同:yank寄存器(“0”)，第一个删除寄存器(“1”)，小删除寄存器(“-”)或任何其他用于删除或删除的寄存器。

唯一的例外是黑洞寄存器。Vim doc说:

An exception is the '_' register: "_dd does not store the deleted text in any
register.

通常，直接使用“0”、“-”和“1-”9默认寄存器或命名寄存器会更好。

如果你想在ex-mode命令中粘贴寄存器的内容，点击<C-r><寄存器字母>。

你为什么要用这个?我想对一个较长的字符串进行搜索和替换，所以我在可视模式下选择了它，开始输入搜索/替换表达式:%s/[PASTE YANKED PHRASE]//g，然后继续我的一天。

如果你只想在ex模式下粘贴一个单词，可以在进入ex模式前确保光标在它上面，然后在ex模式下点击<C-r><C-w>来粘贴单词。

为了更方便:

cnoremap <c-g> <c-r>"
cnoremap <C-Right> <c-r><c-w>

我最喜欢的寄存器是':'寄存器。在正常模式下运行@:可以重复之前运行的ex命令。

所以我们可以用MY_commandXXXXX来验证一些命令，然后把MY_commandXXXXX放在vimrc中
