The menu interface is quite easy to use. Its commands are both
reasonably intuitive and described on screen.
Basically, the menu interface provides a list of boot entries to
the user to choose from. Use the arrow keys to select the entry of
choice, then press <RET> to run it. An optional timeout is
available to boot the default entry (the first one if not set), which is
aborted by pressing any key.
Commands are available to enter a bare command-line by pressing <c>
(which operates exactly like the non-config-file version of GRUB, but
allows one to return to the menu if desired by pressing <ESC>) or to
edit any of the boot entries by pressing <e>.
If you protect the menu interface with a password (see Security),
all you can do is choose an entry by pressing <RET>, or press
<p> to enter the password.
