Go UP - Move

The strangest thing is happening. Why this doesn't work?

Go UP
Copy MOVE
Set FOCUS=dest
GetSizes NODESELECT

It doesn't even execute Go UP. Nothing happens at all. It works only if you select something. Why? I want it to work without selecting anything.

Copy MOVE without any other arguments works on the selection, and needs a selection to be able to run. If nothing is selected the button won't run at all.

If the aim is to move the current folder, use Copy MOVE {sourcepath$} or similar.

But I have this and it works without selecting anything

Go UP
Delete

Why this works? When you Go UP, by default doesn't it select the folder?

I'm not sure why that works. Luck, basically. I would use a more explicit command to avoid surprises.
