+MENU CLEAR
+
+ Clear the screen when exiting the menu, instead of leaving the
+ menu displayed. For vesamenu, this means the graphical
+ background is still displayed without the menu itself for as
+ long as the screen remains in graphics mode.

+MENU SHIFTKEY
+
+ Exit the menu system immediately unless either the Shift or Alt
+ key is pressed, or Caps Lock or Scroll Lock is set.

MENU SEPARATOR
Insert an empty line in the menu.

+MENU RESOLUTION height width
+
+ Requests a specific screen resolution when in graphics mode.
+ The default is "640 480" corresponding to a resolution of
+ 640x480 pixels, which all VGA-compatible monitors should be
+ able to display.
+
+ If the selected resolution is unavailable, the text mode menu
+ is displayed instead.

MENU BACKGROUND background
For vesamenu.c32, sets the background image. The background
can either be a color (see MENU COLOR) or the name of an image

MENU BEGIN [tagname]
non-label. The menu system does not support that.
+MENU SAVE
+MENU NOSAVE
+
+ Remember the last entry selected and make that the default for
+ the next boot. A password-protected menu entry is *not*
+ saved. This requires the ADV data storage mechanism, which is
+ currently only implemented for EXTLINUX, although the other
+ Syslinux derivatives will accept the command (and ignore it.)
+
+ NOTE: MENU SAVE stores the LABEL tag of the selected entry;
+ this mechanism therefore relies on LABEL tags being unique.
+ On the other hand, it handles changes in the configuration
+ file gracefully.
+
+ NOTE: In software RAID-1 setups MENU SAVE only stores the
+ default label on the actual boot disk. This may lead to
+ inconsistent reads from the array, or unexpectedly change the
+ default label after array resynchronization or disk failure.
+
+ The MENU SAVE information can be fully cleared with
+ "extlinux --reset-adv <bootdir>".
+
+ A MENU SAVE or MENU NOSAVE at the top of a (sub)menu affects
+ all entries underneath that (sub)menu except those that in
+ turn have MENU SAVE or MENU NOSAVE declared. This can be used
+ to only save certain entires when selected.
