Q: Cannot reach boot selector screen

With OS 10-3-9, I selected a bad boot device. Now boot fails with msg Input not supported.

How do I get back to the boot selector screen to select the correct boot device? I have no 10.3 bootable disks.

The keyboard is connected via usb only.

This is on a Mac g4, 400 MHZ

Mac Pro, OS X Yosemite (10.10.1), 2012 Mac Pro 5,1 3.2 Ghz, 32 GB of RAM.
