MSYS在windows下模拟了一个类unix的终端

							*gui-mouse-focus*
The 'mousefocus' option can be set to make the keyboard focus follow the
mouse pointer.  This means that the window where the mouse pointer is, is the
active window.  Warning: this doesn't work very well when using a menu,
because the menu command will always be applied to the top window.

If you are on the ':' line (or '/' or '?'), then clicking the left or right
mouse button will position the cursor on the ':' line (if 'mouse' contains
'c', 'a' or 'A').

In any situation the middle mouse button may be clicked to paste the current
selection.


3.2 Selection with Mouse				*gui-mouse-select*

The mouse can be used to start a selection.  How depends on the 'mousemodel'
option:
'mousemodel' is "extend": use the right mouse button
'mousemodel' is "popup":  use the left mouse button, while keeping the Shift
key pressed.

If there was no selection yet, this starts a selection from the old cursor
position to the position pointed to with the mouse.  If there already is a
selection then the closest end will be extended.

If 'selectmode' contains "mouse", then the selection will be in Select mode.
This means that typing normal text will replace the selection.  See
|Select-mode|.  Otherwise, the selection will be in Visual mode.

Double clicking may be done to make the selection word-wise, triple clicking
makes it line-wise, and quadruple clicking makes it rectangular block-wise.

See |gui-selections| on how the selection is used.


3.3 Other Text Selection with Mouse		*gui-mouse-modeless*

When in Command-line mode, at the |hit-return| prompt or whenever the current
mode is not in the 'mouse' option, a different kind of selection is used.
Since Vim continues like the selection isn't there, and there is no mode
associated with the selection, this is called modeless selection.  Any text in
the Vim window can be selected.  Select the text by pressing the left mouse
button at the start, drag to the end and release.  To extend the selection,
use the right mouse button when 'mousemodel' is "extend", or the left mouse
button with the shift key pressed when 'mousemodel' is "popup".
The middle mouse button pasts the text.


3.4 Using Mouse on Status Lines				*gui-mouse-status*

Clicking the left or right mouse button on the status line below a Vim
window makes that window the current window.  The mouse may then be dragged
up and down to move the status line, thus resizing the windows above and
below it.


3.5 Various Mouse Clicks				*gui-mouse-various*

    <S-LeftMouse>	Search forward for the word under the mouse click.
			When 'mousemodel' is "popup" this starts or extends a
			selection.
    <S-RightMouse>	Search backward for the word under the mouse click.
    <C-LeftMouse>	Jump to the tag name under the mouse click.
    <C-RightMouse>	Jump back to position before the previous tag jump
			(same as "CTRL-T")


3.6 Mouse Mappings					*gui-mouse-mapping*

The mouse events, complete with modifiers, may be mapped.  Eg:
>   :map <S-LeftMouse>     <RightMouse>
>   :map <S-LeftDrag>      <RightDrag>
>   :map <S-LeftRelease>   <RightRelease>
>   :map <2-S-LeftMouse>   <2-RightMouse>
>   :map <2-S-LeftDrag>    <2-RightDrag>
>   :map <2-S-LeftRelease> <2-RightRelease>
>   :map <3-S-LeftMouse>   <3-RightMouse>
>   :map <3-S-LeftDrag>    <3-RightDrag>
>   :map <3-S-LeftRelease> <3-RightRelease>
>   :map <4-S-LeftMouse>   <4-RightMouse>
>   :map <4-S-LeftDrag>    <4-RightDrag>
>   :map <4-S-LeftRelease> <4-RightRelease>
These mappings make selection work the way it probably should in a Motif
application, with shift-left mouse allowing for extending the visual area
rather than the right mouse button.

Mouse mapping with modifiers does not work for modeless selection.

==============================================================================
4. Making GUI Selections				*gui-selections*

							*quotestar*
You may make selections with the mouse (see |gui-mouse-select|), or by using
Vim's Visual mode (see |v|).  If 'a' is present in 'guioptions', then
whenever a selection is started (Visual or Select mode), or when the selection
is changed, Vim becomes the owner of the windowing system's primary selection
(on MS-Windows the |gui-clipboard| is used).

There is a special register for storing this selection, it is the "*
register.  Nothing is put in here unless the information about what text is
selected is about to change (eg with a left mouse click somewhere), or when
another application wants to paste the selected text.  Then the text is put
in the "* register.  For example, to cut a line and make it the current
selection/put it on the clipboard:
>	"*dd

Similarly, when you want to paste a selection from another application, e.g.,
by clicking the middle mouse button, the selection is put in the "* register
first, and then 'put' like any other register.  For example, to put the
selection (contents of the clipboard):
>	"*p

Note that when pasting text from one Vim into another separate Vim, the type
of selection (character, line, or block) will also be copied.  For other
applications the type is always character.

When the "unnamed" string is included in the 'clipboard' option, the unnamed
register is the same as the "* register.  Thus you can yank to and paste the
selection without prepending "* to commands.

==============================================================================
5. Menus						*menus*

5.1 Using Menus						*using-menus*

Basically, menus can be used just like mappings.  You can define you own
menus, as many as you like.  There is a default set of menus, so that you
don't have to start from scratch.  Long-time Vim users won't use menus much.
But the power is in adding your own menus and menu items.  They are most
useful for things that you can't remember what the key sequence was.

							*menu.vim*
The default menus are read from the file "$VIMRUNTIME/menu.vim".  See
|$VIMRUNTIME| for where the path comes from.  You can set up your own menus.
Starting off with the default set is a good idea.  You can add more items, or,
if you don't like the defaults at all, start with removing all menus
|:unmenu-all|.  You can also avoid the default menus being loaded by adding
this line to your .vimrc file (NOT your .gvimrc file!):
>	let did_install_default_menus = 1
If you also want to avoid the Syntax menu:
>	let did_install_syntax_menu = 1

The contents of the buffer menu can be controlled by setting the variables
bufmenu_fullpath and bufmenu_maxlen. The former specifies full path of files
to be used in the menu if set to 1. The latter specifies the maximum length of
the path in the menu label. If the path is longer, path elements other than the
first and last are removed. Then trailing and leading characters are removed
from these if necessary.  Last all path elements are removed.  These variables
must be set in .vimrc or similar, since .gvimrc is executed after menu.vim.
Default values are bufmenu_fullpath=0 and bufmenu_maxlen=50.

							*console-menus*
Although this documentation is in the GUI section, you can actually use menus
in console mode too.  You will have to load |menu.vim| explicitly then, it is
not done by default.  You can use the |:emenu| command and command-line
completion with 'wildmenu' to access the menu entries almost like a real menu
system.  To do this, put these commands in your .vimrc file:
>	:source $VIMRUNTIME/menu.vim
>	:set wildmenu
>	:set cpo-=<
>	:set wcm=<C-Z>
>	:map <F4> :emenu <C-Z>
Pressing <F4> will start the menu.  You can now use the cursor keys to select
a menu entry.  Hit <Return> to execute it.  Hit <Esc> if you want to cancel.
This does require the |+menu| feature enabled at compile time.

							*tear-off-menus*
GTK+ and Motif support Tear-off menus.  These are sort of sticky menus or
pop-up menus that are present all the time.  If the resizing does not work
correctly, this may be caused by using something like "Vim*geometry" in de
defaults.  Use "Vim.geometry" instead.

The Win32 GUI version emulates Motif's tear-off menus.  Actually, a Motif user
will spot the differences easily, but hopefully they're just as useful.  You
can also use the |:tearoff| command together with |win32-hidden-menus| to
create floating menus that do not appear on the main menu bar.


5.2 Creating New Menus					*creating-menus*

				*:me*  *:menu*  *:noreme*  *:noremenu*
				*:am*  *:amenu* *:an*      *:anoremenu*
				*:nme* *:nmenu* *:nnoreme* *:nnoremenu*
				*:ome* *:omenu* *:onoreme* *:onoremenu*
				*:vme* *:vmenu* *:vnoreme* *:vnoremenu*
				*:ime* *:imenu* *:inoreme* *:inoremenu*
				*:cme* *:cmenu* *:cnoreme* *:cnoremenu*
To create a new menu item, use the ":menu" commands.  They are exactly like
the ":map" set of commands but the first argument is a menu item name, given
as a path of menus and submenus with a '.' between them. eg:
>   :menu File.Save  :w<CR>
>   :inoremenu File.Save  <C-O>:w<CR>
>   :menu Edit.Big\ Changes.Delete\ All\ Spaces  :%s/[ ^I]//g<CR>

This last one will create a new item in the menu bar called "Edit", holding
the mouse button down on this will pop up a menu containing the item
"Big Changes", which is a sub-menu containing the item "Delete All Spaces",
which when selected, performs the operation.

Special characters in a menu name:
	&	The next character is the shortcut key.  Make sure each
		shortcut key is only used once in a (sub)menu.
	<Tab>	Separates the menu name from right-aligned text.  This can be
		used to show the equivalent typed command.  The text "<Tab>"
		can be used here for convenience.  If you are using a real
		Tab, don't forget to put a backslash before it!
Example:
>   :amenu &File.&Open<Tab>:e  :browse e<CR>
[typed literally]
With the shortcut "F" (while keeping the <Alt> key pressed), and then "O",
this menu can be used.  The second part is shown as "Open     :e".  The ":e"
is right aligned, and the "O" is underlined, to indicate it is the shortcut.

The ":amenu" command can be used to define menu entries for all modes at once.
To make the command work correctly, a character is automatically inserted for
some modes:
	mode		inserted	~
	Normal		nothing
	Visual		<Esc>
	Insert		<C-O>
	Cmdline		<C-C>
	Op-pending	<Esc>

Example:
>   :amenu File.Exit	:qa!^M
is equal to:
>   :nmenu File.Exit	:qa!^M
>   :vmenu File.Exit	^[:qa!^M
>   :imenu File.Exit	^O:qa!^M
>   :cmenu File.Exit	^C:qa!^M
>   :omenu File.Exit	^[:qa!^M

Careful: In Insert mode this only works for a SINGLE Normal mode command,
because of the CTRL-O.  If you have two or more commands, you will need to use
the ":imenu" command.  For inserting text in any mode, you can use the
expression register:
>   :amenu Insert.foobar   "='foobar'<CR>P

Note that the '<' and 'k' flags in 'cpoptions' also apply here (when
included they make the <> form and raw key codes not being recognized).

Note that <Esc> in Cmdline mode executes the command, like in a mapping.  This
is Vi compatible.  Use CTRL-C to quit Cmdline mode.

							*menu-priority*
You can give a priority to a menu.  Menus with a higher priority go more to
the right.  The priority is given as a number before the ":menu" command.
Example:
