If you have not tried this, fiddle with the following combination
of keys; the Ctrl key + the mouse wheel, and the Alt key + the
mouse wheel. Work with them separately. I tried Century a monent
ago and when it came up on screen for the first time, it was a
disaster. However, I gained control of the situation by pressing
the Ctrl key and the wheel first. That make the characters readable,
and then I set the space between the characters to something I
thought was agreeable with the Alt key and the wheel.
