What is the name of the concept or type of key used in shifting characters on a mobile device?
Many common virtual keyboards used in cellphones and advanced mobile devices use a certain paradigm for dealing with shifted characters:
- Hitting shift once results in it being depressed for one character - i.e. until the next regular keypress
- Hitting shift a second time locks the shift key indefinitely through multiple keypresses, as with Caps Lock.
- Hitting shift a third time undoes the lock from the second press.
What is it called when the shift key is used this way? Is it called both "Shift" and "Caps Lock" at the same time? It has some similarities to the StickyKeys system used by Windows - is it called a "sticky" system of some sort? Is it a "Shift Lock" or a "Sticky Lock?"
