A message arrived under my rock, a couple of months ago. It said, "If you hold down "ctrl" while scrolling the mouse wheel, it is possible to easily and quickly vary the screen zoom between 25% and 500% of normal.".
I have only mentioned this to one other person, and she hadn't been aware of it, either. Just in case we weren't actually the last two persons to get the memo, I mention it here; it's very useful, and I use quite it often.
If you vote for government, you have no right to complain about what government does.
