HAVING TROUBLE INPUTTING "SQUARE BRACKET" SYMBOL TO PROGRAM CINTIQ PRO 24 EXPRESS KEY REMOTE

Hi,

After some trial and error, I managed to partially figure out how to program my Express Key Remote to my Cintiq Pro 24. But after several attempts to program one of the functions -- it won't allow me to input a Square Bracket for this command: "Shift + [".       ....Instead, it puts a Curly Bracket Brace: "{", in it's place.

QUESTION: How can I get the dialog box to accept the Square Bracket "[", following inputting: "Shift"?

Best,

-Mark
