I'm working on a system recovery mechanism that runs in the linuxrc file that will restore a corrupted system. I need to do it by detecting that the user is pressing a certain key sequence (such as CTRL-ALT-BACKSPACE). Since the user may start pressing that key sequence while the kernel is booting, how can I detect the make codes for the CTRL and ALT keys? (The BACKSPACE key is easy enough to see since the keyboard in autorepeat mode repeats the last key pressed.) I'm already reading from the keyboard in RAW mode, but is there another way to check the state of the modifier keys?
