我在我的.vimrc中添加了以下一行

nnoremap <F5> :%y+<CR>

这允许我通过按F5(在命令模式下)将Vim中的所有文本复制到剪贴板。

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

单击鼠标左键，拖过要复制和释放的部分。代码自动复制到剪贴板。

您可以使用“cat”命令打开文件，并使用鼠标复制

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.

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
