OK.. for others who are arriving with the same issue - we worked it out...
FN+Del for three seconds does the reset :)
FN+PrtScrn cycles through RGB colour modes
FN+ numbers 1-5 sets alternate modes for cursor keys switching with AWSD etc.
Hope that helps someone else!
Hi All
My son has accidentally set his keyboard into a mode that switches the cursor and AWSD keys. Trying different FN+ number keys cycles through a few alternate options but doesn't reset to the standard. Is there a PDF manual or written list of FN keyboard shortcuts anywhere, so we can learn...
