I am a gamer, not hardcore but more than casual. I have a problem with keeping or returning my fingers/hand to the W,A,S,D keys to just move my character after using other keys near them for abilities. My keyboard is the SteelSeries Apex and it has two(2) raised dots on the W key as well as the usual raised marks on the F & J keys. Unfortunately mt finger tips are not sensitive enough to feel these as I spent 20+ years as an auto mechanic. Is there any way I could modify the W or S key so I could recognize them by touch?
