i touch a random key on my exposed / slid out qwerty to reactivate the turned off LCD screen. some keys activate the screen, and some don't. this also changes from time to time...!? for example the "G" key always seems to work for this, but the "L" or the "Z" will only reactivate the screen it it was turned off recently like a minute ago, but not if it was turned off many minutes ago. rule of thumb (no pun intended), the closer you are to the center of the keyboard, the more likely that key will turn on the screen. so the question is... what's up with this weird intermittent formula, why do some keys always work and some other keys only sometimes work?
