so.....is it correct to assume that it is not possible to create a hotkey combination in Autohotkey that is based on pressing two keys in rapid succession?

If the drive is write protected, would I have to worry about any of these infections?

I use Keypass every day, and loaded the portable version on my usb mainly because it stores my passwords.  But what protection does that provide against keyloggers or screenwatchers?

p.s.  All the 'important' information on the usb is stored in encrypted True Crypt hidden volumes, in the event I were to lose the usb stick.
