Thread:VisualEditor/Feedback/Special characters/reply (7)

"I was not referring to character input though, it was a more general question"

I think the user was responding to the general request for input on the character input tool, rather than your question, and just responded on the wrong thread; I've moved it here instead.

"In my specific case this would be a custom popup dialog (action: dialog) that inserts a link to a picture recently uploaded by the editing user."

Interesting! It was suggested in bug 60398 that we do this in VisualEditor itself, and there's a work in progress commit to do this which you might be interested in.
