F1-F2-F3 options

I'm not sure if it is a right brain or left brain thing but my curiosity has gotten me. The majority of the time I will click the Fold, Check or Raise prompt on the screen when it is my turn to act. Also notice the F1, F2,F3 buttons associated with those choices. Do more of you choose the prompts or use the keyboard to make your choices. I have found in my case that a fast table I use the keyboard to prevent from clicking the wrong choice, makes me think about my choices a little longer that way. The slower tables give me more time to pick the proper prompt. Or maybe I just need to get better at it. LOL Tks.
