Photoshop - how to adjust selection area size?

[usagora]

Been using GIMP for many years, but unfortunately it's broken in Big Sur, because the way windows are redrawn apparently has changed, which results in no selections being visible in GIMP (you can't see the "marching ant" outline of selections). I've waited months for it to be fixed, but it's still broken, so I finally broke down and subscribed to the PS/LR Adobe bundle.

So in GIMP, when I made a rectangular selection, it was really easy to adjust the selection area size after the fact by clicking and dragging any corner or side of the selection. For example, when you hover over the top right corner of a selection with the cursor, you'd see this:

So how do you do the same thing in Photoshop? Do you have to press a key to make similar adjustment "handles" visible? All I seem to be able to do is move the selection once it's made.

By the way, I just found a bug in Photoshop for macOS. I made a selection in an empty area of the canvas and under Properties > Transform on the right, I changed the width. An error message popped up stating "Could not transform the selected pixels because the selected area is empty." But when I click "OK" or press the Esc key to dismiss it, it keeps popping back up. There's no way to get rid of it, and you can't do anything else because it's persistent. The only thing you can do is force-quit the app. See video below (I've also posted this on the Photoshop feedback forum):

It is simple. To change the size of the area first chosen, right click in the chosen area and select free transform. Change the size to what you need and hit the check mark or return. Voila done!

If you mean change the selcted area without affecting your image, right click inside the selection and select Transform Selection. I’m sure there’s a hotkey but my muscle memory can’t find it today.

THIS is what I mean. Thank you! I also noticed that by default it transforms the same aspect ratio. To freely transform, you have to hold down the Shift key. Holding down the Cmd key allows you to change the angles of the sides to make other trapezoids.
