Ah, that’s good, but a bit tricky. If one holds down too long, iPadOS thinks you want to go into multi-window mode (not sure if that’s the right terminology). But a quick tap on the radio button and immediate slide down the list will scroll all the way down, selecting each item as you go. Quite nice.

Perhaps a quicker fix would be to add this tip to the Documentation right after this line:

Before someone closes this with a dismissive response, “just use the Files app to do mass moving”, I have to add context. The context here is that I’m trying to move a third-party Swift package into Playground’s Pages/[some name].xcplaygroundpage folder. Such folders are not accessible in the Files app. 

I specifically bought Textastic for this ability to peer into such folders and move files around, based on this article: 

(I imagine I might find Textastic’s code editing features useful sooner or later. Smiley needed?)
