Is there any way to get the value of the pressed key, to use in an expression? If this were possible, it would be easy to use variables to set the value of a text input dynamically, using an expression 'On Key/GamePad, set variable {fieldvalue} to {fieldvalue} + {key pressed}. Or a slightly more complex expression to deal with backspace. Therefore creating typeable form inputs, something that has been requested for a long time.

This seems like something that would be relatively simple to add, if not currently available?
