I see these highlighted cursors all the time on YouTube, but trying to find out how to do it wasn’t easy. It’s so easy to loose track of that mouse pointer in a video. Install some obscure package or some double talk answer. It seemed almost like it was some trade secret. After some digging. I found this link. Better yet…let’s cut to the chase and just go here, download, extract and move to your .icon directory. Not the big containing folder …the individual cursor folders. There were about 7 different colors for the highlight. I wanted yellow but it looked pea green on my screen. Then select from mouse pointer, where your Themes setting is.
