I have a widescreen with a monitor split set up like pillar boxes - a big central area and a thinner side area on each flank.

Sometimes a browser window on one of these flanks is too thin and I need to expand it to 50% screen size, basically like hitting win key + left arrow to snap it to the left half of the screen.

Is it possible to:
1) Make this a toggle, e.g. hotkey that pressed once brings to 50% screen-left, pressed again resumes to original position?

2) Map this to the Mouse Scroll button right/left clicks? What I mean by this is my house scroll wheel has the click down, but also the click left and click right features that I don't use for anything.

Ideally when I'm using the left pillar window I'd click right to expand it and left to return to original, and vice versa on the right.

That's extremely generous of you, thank you very much. File is attached.

I will look to see if the Logitech software or some other 3rd party can map the scroll left/right to another command and then piggyback off that.

Thank you again, the support on this forum is on another level.

First off thanks again. As someone in a tech support-adjacent field I cringe at the thought of asking a follow up request to free work.

The first part of the scripts do what I want, expand the window. After that though, it cycles through my monitor splits which is not needed, I just want it to jump back to the original position.

I have attached a video of the scripts in action.

Time Stamps:
00:01 - a peek at my triple panel monitor config.
00:10 - cycling through the scroll left-to-right script.
Note - ultimately it stays on maximized, I then return it to a smaller window manually.
00:35 - repeating the same proces for the right-to-left script
00:48 - My desired function - Left panel expands to half screen by script (so far so good), but then resizing back to the left panel original position, which I have to do manually.

This is beautiful. C'mere I'm gonna kiss you on the mouth.
