No undo in code editor?

[Astralite]

So, I highlight a bunch of code I want to comment out temporarily...instead of hitting ctrl-K, I accidently hit shift-K...all my code turns into just "K", no undo option...it's all gone..

more than a little annoying...you'd think Undo would be a thing while editing code.

I just tried it and it worked properly. Tried you example of shift + k and then ctrl + z undid it. Tried just deleting text and ctrl + z undid that also.

This is for the steam version 2.0.5.92. I see you don't have a mouse symbol next to your name which means you don't have GMS2 on your steam account. Maybe check for a newer version or patch if you are using the version from Yoyo.

Under file > preferences > text editors > code editor - way down near the bottom there is a field for undo/redo stack limit (<0 unlimited). Mine is set to -1 so I guess unlimited undos?

I tested it also and have the same issue, there is an undo option but its never usable, i can do what i want, i think its an option in gms2 or windows which deactivates it but i don't know what

UNDO still not working!
We need an update to GM 2 Desktop urgently!
