Can't access boot menu

[badogski29]

I did an upgrade from 12.0-U8 to 13.0-U2 but it failed. Tried changing the boot environment using the boot menu on startup but it just loads straight to Truenas. I tried all the hotkeys I found on the internet (shift, Esc, space), but none of them worked. What is odd though is I can access it through Serial (SOL IPMITOOL).

Fortunately I was able to change environment using beadm since shell still worked, but it would be nice to get access to the boot menu in case I lose shell access next time this happens.
