Reader Alec Thompson sent me this. It was a tip he received from Dot Martin:
Great keyboard trick! [If you have a mouse with a wheel]
Try this – It really works!
I just found out about this. Thought I’d pass this on.
It’s very useful when trying to read small e-mail print
(especially in the early hours).
If you hold down the Ctrl key on your key board and turn the small wheel in the middle of your mouse, the print size will change – it will either get larger or smaller – depending on which way you turn the wheel.
