Ctrl + Shift + T randomly triggers some screenshot function

Hi, I've been using Studio 2024 for less than a week but I'm already experiencing things I cannot explain. Perhaps somebody can.

The Ctrl + Shift + T shortcut doesn't always work. Sometimes it triggers a screen capture function (which otherwise I haven't even found in the documentation and I know that this combination is not assigned to anything else but the Split segment command). Why is it happening? Have I activated some alternative mode in Trados?

Thanks,

Zoltán
