When I write answers I do one click things and then add the geek stuff at the bottom of the answers in a sort of "and for those of you who like to copy and paste have this part too."

I would say an ideal answer would have both, but present the GUI-friendly way first, and the CLI way as a reference at the bottom.

Editing out the PPA text instructions is probably not a good edit, as by definition adding and managing PPAs is expert territory so we might as well give them all the instructions.

It also depends on the question. If someone is asking how to do something graphically then I just do it with screenshots. If it's something server related then it would be reversed, you would probably favor a CLI answer.
