The ESCAPE key does nothing more than generate an interrupt when pressed, and
responds to queries on row 7, column 0 of the keyboard matrix. Everything else
should be performed by the OS for us, so we can safely ignore it :-)

I agree with you here! Although I find the index of osbytes particularly
useful. Especially when you see for instance:

LDA &25A

I usually do a quick 25A-236+A6 => CA, which the index tells me is read/write
keyboard status.
