That's a nice link for showing keyboard shortcuts, but ti doesn't fix my problem.
It's not that I'm looking for a shortcut, it's that the new versions do not register any keystrokes in the dialog box.
Normally when the box pops up asking to continue or cancel, it gives the box focus and the dotted lines around the continue button means it's selected, then you can use the arrow keys to move back and fourth between the two.
In the new versions of Iron, it doesn't do that. and if I click on the box (not one of the buttons) just to make sure the dialogue box is given focus I still cannot use ANY keystrokes to make anything happen to the box.
