I recently learned some Mac tips and one of the things I was excited about and tried is Hot Corners. But after a few months of trying them they proved to be Annoying Corners. I often accidentally send my mouse pointer to one of the corners of the screen and invoke them inadvertently. So I disabled Hot Corners today.
I am hoping to instead add a few more multi-touch gestures to my finger memory. Multi-touch gestures are intuitive, fun, and make me feel like I am a pro Mac Book Pro user. So far I am loving the gestures which means I will practice them more.
