gVim:

:set go=a

ggVG

看:help go-a:

'a' Autoselect:  If present, then whenever VISUAL mode is started,
 or the Visual area extended, Vim tries to become the owner of
 the windowing system's global selection.  This means that the
 Visually highlighted text is available for pasting into other
 applications as well as into Vim itself.  When the Visual mode
 ends, possibly due to an operation on the text, or when an
 application wants to paste the selection, the highlighted text
 is automatically yanked into the "* selection register.
 Thus the selection is still available for pasting into other
 applications after the VISUAL mode has ended.
     If not present, then Vim won't become the owner of the
 windowing system's global selection unless explicitly told to
 by a yank or delete operation for the "* register.
 The same applies to the modeless selection.

在vim或它的选项卡中复制整个文件吗

y G 

然后移动到一个标签和粘贴

p

并对整个文件进行删减使用

d G

如果您的手指默认使用CTRL-A CTRL-C，那么尝试从$VIMRUNTIME/mswin.vim映射。

" CTRL-C and CTRL-Insert are Copy
vnoremap <C-C> "+y

" CTRL-A is Select all
noremap <C-A> gggH<C-O>G
inoremap <C-A> <C-O>gg<C-O>gH<C-O>G
cnoremap <C-A> <C-C>gggH<C-O>G
onoremap <C-A> <C-C>gggH<C-O>G
snoremap <C-A> <C-C>gggH<C-O>G
xnoremap <C-A> <C-C>ggVG

我将它们映射到<Leader><C-a>和<Leader><C-c>。

剪贴板为buffer +。要复制到剪贴板，请执行“+y和[移动]”。

gg"+yG会复制整个文件。

类似地，要从剪贴板粘贴，“+p

非常简单的办法:

如果你在Windows中，想要将整个文本复制到本地剪贴板，而不是你正在使用的远程服务器缓冲区，不需要任何额外的工具，只需:

放大，在屏幕上看到整个文件文本 用鼠标选择它们，然后右击复制到您的本地剪贴板

注1:现在在许多终端(如窗口终端)上，你可以用ctrl++/ctrl+-放大/缩小，用ctrl+0重置缩放大小

注2:如果你的vim是编号文件行，你可以:设置nonnumber
