Edit selection

[Dupond]

Hello!

Is it possible to edit a selection? For example, I'd like to use slop to select a part of the screen, then edit my selection before passing the coordinates to maim.

I've seen this comment, but it's not exactly what I want:

• I select an area;
• before releasing the mouse button, I press and hold the space key;
• now I can move the selection (as explained in this post), but it doesn't allow me to edit it...

Thank you very much for your help!
