You really have a hand for posting stuff that I’d like to add to my reading list. Already wanted to comment the last time, but never get around to. Thanks, all stuff I would have never looked at on my own - I appreciate it.

Are you driving? Did you ever have the impulse to just jerk your steering wheel and crash into that tree rapidly approaching at 120mph?

The comic plays off of that.

Have you considered creating a macro in any image editor that supports macros and assigning that to a button / keyboard shortcut?

gimp certainly has macros and scripting features. Maybe this will help: https://www.gimp.org/tutorials/Automate_Editing_in_GIMP/

You can still edit a mask / selection with the regular UI, then trigger the cut/merge process you desire based on that selection.

As someone who often lifts a finger, types out the first two sentences of a comment and then just resigns: thanks for the well-written comment.
