They are much smaller. There is also no backlighting for these buttons unlike the remotes in the Pronto NG line. I would have liked to see the Firm keys twice the height they are now and with backlighting. I use the firm keys for transport controls as well and find it best to just activate the screen first when needing to access Firm keys 2-4 using the Firm key labels as a guide. I tend to always activate the screen first when going to use Firm key 3 in particular. Firm keys 1 and 5 are on the ends and are the only ones I choose to use by feel alone each and every time without activating the screen first.
