I have the mod installed and it appears to be working just fine but for the life of me, I can not get this feature to work. I am using forge to load it.

I believe it is something to do with my keyboard but not sure. I am pretty new to mods and would love some insight into what some common pitfalls are with this feature.

pressing control+alt+printscreen works fine on my keyboard for screenshots...
within minecraft I can press a special key and f2 to get a screenshot just fine but control+shift and printscreen does nothing....

thoughts?

Have you tried pressing Ctrl + Shift + F2?

Did you remove this?

It's not been ported to 1.14+ yet.

Any update on this? Still not working in 1.16+?
