Can I reduce the size of the print on my computer screen, e.g. when I am looking at the Answerbank, I would prefer a smaller type size to get more information on the screen. Thank you.
Ctrl plus the Minus key on the numeric pad, or Ctrl and the Scroll-wheel on the mouse. But AB's layout is adpative, so the maximum you will see horizontally is fixed. (For example, the maximum that the first line of your question can become will be "Can I reduce the size of the print on my computer screen, e.g. when I am")
