Vim 8.0 於 Linux 的 CLI 環境，使用滑鼠選取文字的話，預設不是 Xwindow 的選取方式，而是 Vim 內部的選取方式(v)，所以文字要複製沒辦法使用 Ctrl + c 等等複製到系統的記憶體。
- 註1：預設為 set mouse=a 的模式
- 註2：Debian stretch 目前安裝就是 Vim 8.0，就會遇到此情況
想要複製到系統的記憶體，可以使用下述兩種方式：
- 按住 Shift 後，在用滑鼠選取，可以使用 Ctrl + c 複製，或 此時用滑鼠中間就可以貼上。(再按一下 Shift 選取反白才會消失)
- :set mouse= 或 :set mouse=r 或 :set mouse=v (設定不要為 a 就可以使用標準系統的選取、複製模式)

- clipboard - Copy-paste for vim is not working when mouse (:set mouse=a) is on?
- Vim documentation: options
*'mouse'* *E538*
'mouse' string (default "", "a" for GUI, MS-DOS and Win32)
global
{not in Vi}
Enable the use of the mouse. Only works for certain terminals
(xterm, MS-DOS, Win32 |win32-mouse|, QNX pterm, *BSD console with
sysmouse and Linux console with gpm). For using the mouse in the
GUI, see |gui-mouse|.
The mouse can be enabled for different modes:
n Normal mode
v Visual mode
i Insert mode
c Command-line mode
h all previous modes when editing a help file
a all previous modes
r for |hit-enter| and |more-prompt| prompt
Normally you would enable the mouse in all four modes with:
:set mouse=a
When the mouse is not enabled, the GUI will still use the mouse for
modeless selection. This doesn't move the text cursor.
See |mouse-using|. Also see |'clipboard'|.
Note: When enabling the mouse in a terminal, copy/paste will use the
"* register if there is access to an X-server. The xterm handling of
the mouse buttons can still be used by keeping the shift key pressed.
Also see the 'clipboard' option.
