Hello,
PennController should automatically detect when the argument is an actual number, or a string exclusively consisting of digits. Visibly it fails to do so, and therefore expects a keypress producing the character with code 12, which is inaccessible in a single keystroke.
To fool PennController, add a dummy non-digit character to your digit string, for example � (this one’s called the “replacement character,” I doubt anyone would have configured their keyboard to type it in a single keystroke):
newKey("1or2", "�12")
.wait()
.test.pressed("1")
.success( newText("success", "You're right!").print() )
.failure( newText("failure", "You're wrong, 0.999... and 1 do refer to the same number").print() )
