Dope sheet: How to know what frame a selected key is on?

Simple question: in Dope Sheet mode of Track View, is there a way to
tell on what frame the currently selected key is?  The only way I can
find is to drag it a bit, whereupon the info shows in a little
tooltip--which is kind of pointless because then it's not on that frame
anymore.  I would expect it to display in the slot at the bottom, like
it does in Curve editor...then I could also type in a new number rather

Never mind--just realized I have Modify Subtree Keys on; the frame
number only shows up if I drill down and select them in the bottom
level.  It would be nice if it did display it, though; it would make
this mode really handy!
