I was typing a document and it went to a postage stamp size and I can not get it to go back to full size.
Have you looked at the bottom-right corner of the window? There is a percentage, e.g., 1% or 50%. Right-click that, and then you should be able to select 100%.
Otherwise, just next to the percentage is a slider. Just move it and it should resize easily.
Another option is to open the “View” menu, and then select “Zoom”.
Please let me know if you were able to find these options…
