It's just not easy to do the 3 finger solute with one hand on my HP laptop. I know I have short fingers (the reason why I gave up playing the piano), but even on a normal keyboard with normal fingers, it is an unnatural combination to do with one hand.
I have two hands, why does this bother me so much? Because I have a 5 minute screen saver setting and when I start talking to someone on the phone, the screen saver kicks in. Near the end of my phone conversation is usually when I need to book an appointment or create a task while holding the phone in one hand I have to try and unlock the computer with the other (my password is already optimised for one handed entry).
The answer is to swap some keys around. E.g.
Who uses the right click key anyway? Get this simple little application from http://www.inchwest.com and get MapKeyboard.
You only have to run this 30Kb application one time and the settings are saved.
