If i were to purchase a Wyse keyboard to take caps from wich model would i want if i was going to use them on a Filco Tenkeyless Majestouch 2 with blues? Would it be the Wyse PC Enhanced Keyboard-Gray-12 function part #840358-01? If i am incorrect please tell me wich one would fit my keyboard the best since most have some funky shaped caps compared to my Filco.
