I agree, much cleaner and easier to follow and write, so long as you
don't forget to exit each of the case statements so as not to have
subsequent ones executed as well. I believe this is a feature in Rev,
though I'd prefer if it weren't.

for me a great advantage of SWITCH is the opportunity for fast and
easy multiple if statements done this way instead:
SWITCH pKey
CASE "B"
CASE return

easy to read, easy to write.
I haven't timed it - but if it's read by the engine in the same
manner other programming languages handle it then it would be
faster as any subsequent conditions are skipped because once the
case statement (switch statement) is met the compiler knows not to
proceed - as opposed to if/then/else etc where the entire handler
is evaluated in full.
