So just started having this issue where when you do Ctrl+Shift+down arrow, (where it will highlight all the cells below it) stopped working. The odd thing is it works on Ctrl +Shft +Right Arrow as well as Up and left. Also, it works fine on the right side of the keyboard just not the left. Additionally, the ctrl and shift buttons work fine in all other configurations, just Ctrl+Shift+down arrow (on left side of keyboard) does not work. Is there some hidden lock that would do this? It is a keyboard issue as I tried on multiple computers and same issue. Used alternate keyboard and it worked fine. This keyboard has worked fine (had for 3 months) prior to today. I tried the reset on the software but that seems to only reset key macros I guess. Is there a reset entire Keyboard to manufacturer defaults?
Oh and I have the Challenger Prime.
