Ok, I just had to do this too!

Corel PaintShop Pro (PSP for short) rivals Photoshop since the beginning of time, but it only runs on Windows. If you've moved to Linux or macOS (or use them on the side) you are probably using Gimp as a PSP alternative. These keyboard & mouse bindings will hopefully get your life a little easier, until you fully adopt to Gimp's native way of doing things.

As far as I know and as of this writing, these are the most up to date, and frankly the only PaintShop Pro bindings for Gimp, available anywhere (there is also an on-line reference, as a Google Sheet).

PS. I recently did a similar thing for Photoshop, so I just had to do it for PSP too
