Now. If I remove the solder blob, and solder in a couple of jumper pins. Would this be possible to insert a switch from a PC-Case and if the switch is a momentary off switch, then I would actually be able to use both the switch and the keyboard. Are my reading of the schematics correct?
I may be wrong, but my reading of that schematic is that breaking jp1 and soldering a switch across it would would cause the power on reset to only work if you held your button & the button would only work during power on.
