Enable the use of the mouse. Only works for certain terminals
(xterm, MS-DOS, Win32 |win32-mouse|, qnx pterm, 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
A auto-select in Visual mode
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.
