The difference between the file> Close and: close in Vim

Question

I opened _gvimrc from the Vim HOME folder.
Made a little editing.
Disabled from edit mode.
Completed :w to save changes.
Then he tried to close the file by doing :close , but he says E444: Cannot close last window

If I go to the "File" menu and click on the Close menu item (which says :close next to it), then it closes normally.

Why does File> Close successfully close the file, but :close does not work?

---

EDIT

This is my File menu:

Answer 1

from :he :close :

CTRL-W c *CTRL-W_c* *:clo* *:close* :clo[se][!] Close current window. When the 'hidden' option is set, or when the buffer was changed and the [!] is used, the buffer becomes hidden (unless there is another window editing it). When there is only one window in the current tab page and there is another tab page, this closes the current tab page. |tab-page|. This command fails when: *E444* - There is only one window on the screen. - When 'hidden' is not set, [!] is not used, the buffer has changes, and there is no other window on this buffer. Changes to the buffer are not written and won't get lost, so this is a "safe" command.

basically, the close window menu item is incorrect and corresponds to what is actually :quit closes the current window, or the current vim session if this is the last window:

*:q* *:quit* :q[uit] Quit the current window. Quit Vim if this is the last window. This fails when changes have been made and Vim refuses to |abandon| the current buffer, and when the last file in the argument list has not been edited. If there are other tab pages and quitting the last window in the current tab page the current tab page is closed |tab-page|. Triggers the |QuitPre| autocommand event.

and IINW, it's actually :confirm quit . Therefore, if you are correct that :close next to the close menu option is definitely a typo that needs to be fixed.

EDIT:

ok, just talked to some people on the #vim IRC channel. There they informed me about the command :menu , from where you can access the command file-> close, through :menu File.Close :

 To create a new menu item, use the ":menu" commands. They are mostly 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 <CO>:w<CR> :menu Edit.Big\ Changes.Delete\ All\ Spaces :%s/[ ^I]//g<CR> 

The close operation is definitely not :close , but the built-in menu for WinClose ( BuiltIn17 ) BuiltIn17 :he builtin-tools . He does things differently than :close .

But in any case, this error / typo is separate, if you are new to vim, you better learn how to use it without a menu. All you need is under your fingertips. Go through vimtutor , play vimgolf , read a few tutorials and try to learn and use one new command every month. You will be more productive and forget about your mouse ...
