keystroke
Insert keystrokes into the keyboard buffer when booting. Sometimes an
operating system or chainloaded boot loader requires particular keys to be
pressed: for example, one might need to press a particular key to enter
"safe mode", or when chainloading another boot loader one might send
keystrokes to it to navigate its menu.
You may provide up to 16 keystrokes (the length of the BIOS keyboard
buffer). Keystroke names may be upper-case or lower-case letters, digits,
or taken from the following table:
@c Please keep this table in the same order as in
@c commands/i386/pc/sendkey.c, for ease of maintenance.

As well as keystrokes, the @command{sendkey} command takes various options
that affect the BIOS keyboard status flags. These options take an @samp{on}
or @samp{off} parameter, specifying that the corresponding status flag be
set or unset; omitting the option for a given status flag will leave that
flag at its initial state at boot. The @option{--num}, @option{--caps},
@option{--scroll}, and @option{--insert} options emulate setting the
corresponding mode, while the @option{--numkey}, @option{--capskey},
@option{--scrollkey}, and @option{--insertkey} options emulate pressing and
holding the corresponding key. The other status flag options are
self-explanatory.
If the @option{--no-led} option is given, the status flag options will have
no effect on keyboard LEDs.
If the @command{sendkey} command is given multiple times, then only the last
invocation has any effect.
Since @command{sendkey} manipulates the BIOS keyboard buffer, it may cause
hangs, reboots, or other misbehaviour on some systems. If the operating
system or boot loader that runs after GRUB uses its own keyboard driver
rather than the BIOS keyboard functions, then @command{sendkey} will have no
effect.
This command is only available on PC BIOS systems.
