How to make transparent the outer part of a rectangle

How can I make transparent the outer part of a rectangle?
I tried the Background eraser, but it made the selection transparent unevenly.

I tried the Layers > opacity slider, but that made the whole layer transparent.

I referred to Photoshop’s Help and Adobe.com knowledge base, but the closest I got there was clipping paths, which is only appropriate for exported graphics.

Select the rectangle? invert selection (CTRL+CAPS+I)?, cut the new selection (CTRL+X)? add a new transparent layer underneath? or maybe I misunderstood the problem…But I must know if your rectangle is a path, a"brush stoke", or whatever to tell about the better way to select it (and then invert)

P.S: In fact you’re the first person I’ve ever ever ever heard whom ever ever ever used the background eraser (but it’s not a proof that’s a useless tool).

I never use it myself but some years ago I saw a video demontraded how the background eraser works and it seems kinda handy for something .. but I have no need for it so I forgot all about it until I read this thread.

How long were you there?

Nearly one year and a half ( 8 months in Brighton, 8 months Toulouse, 16 months of rain and depression)
I just reinstalled my old CS on the computer one week ago, remove the restoration and color management books from the boxes, plug the Wacom again and "roule ma poule".

How long were you there?

You have to use a layer mask. Highlight the layer you want to make transparent and click the layer mask icon on your layers palet. It’s just a matter of adding a black/white gradient to that mask.

Transparent In/Outside of the circle, square, rectangle etc. the just like the man said, no need any fancier command but to mark the rectangle area then inverse and DEL the select area should do.
