I am not sure if this is possible with label (hopefully someone more expertised comes along) but it could be done using text box and cursor location i guess.
It would be nice if you could explain better what you want to do.
You can make a label clickable, and then when you click you assign the text it has to a variable or another label or whatever… If you want to do something else you should explain better what you need…
Thank you for your greating. Your extension is super but i need the same like in the video bellow. The idea is to have the start selection by one click and having the end of a selection by clicking a second times to have a selection part of a any text. Hope u understand my request and have a solution to suggest. Thanks Guys
