In the Print menu I accidentally pushed the Rotate button. The text on the button turned red and now when I use Quick Layout the printed sheet is rotated.
OK, that's what Rotate is probably for.
But how do I get back to "normal" orientation? There doesn't seem to be an un-rotate command.
Thanks for the hint. When I click the Rotate button again, it asks me to define the center of rotation. Pick anywhere. Then it gives me a list where one choice is "Clear Value". I clicked that and now it all works as normal.
Another of the great features of this forum is my history remains available. If I forget how I did something ten years ago, I can view my posts and re-find the answer.
