You can use the  `read`  command also to pause execution:

set pager=1
cat ($root)/boot/grub/MESSAGE.txt
unset pager
echo -n "-- Press ENTER to continue: "

the solution which is available atm is:

set pager=1
cat ($root)/boot/grub/MESSAGE.txt
unset pager
echo -n "-- Press ESC or wait 60 sec to continue: "
sleep --verbose --interruptible  60

There is no pause command. To stop for a minute before showing the menu: sleep continues on Escape key only.

In the Debian installer we'd like to have a help screen at the boot menu, to document some useful boot options etc., so we would like to have some command which allows to show some text (bigger than a screen), for instance a more/less command.
