Earlier quoted context omitted.
I still remember that time I tried selecting something and moving the pixels of my selection, rather than the whole layer in GIMP. I ended up having to google it and it was a 3-key combination shortcut. I don't remember how to do it in photoshop, but I'm pretty sure I didn't have to google "how to move a selection" that time I used it.
Fair. I think you’re expected to float the selection into a new layer and then move the layer, but this is such a common operation for people to want that it ought to be directly available from the Move tool.
I did not know another way existed... which also just illustrates the point.
