how to view selection size?

In CS2 and in Photoshop Elements 6, I am trying to determine how to
get PS to display the dimensional size (in pixels: H x W) of a
selection *while* creating/dragging the selection. I am relatively
novice user of PS, and I've just assumed it would have this
capability, but have not been able to find it. If it does not, can
anyone suggest a technique or workaround to accomplish the same
result?

thanks
