Strange feature of POWERPOINT

[flyaway]

What is the use of the menu bar option circled by a green brush（更多/more）? I clicked but didn't respond.

Cannot replicate the issue here, can you share the problem still and the version of Office?

To replicate the issue here, you need to use ctrl A to select all the contents in a text box, and then right-click the selected text to pop up this menu.
