I've posted this to the forum, but would appreciate any further help you are able to provide.
Q. Is it possible to toggle the display on and off scripted to a single mouse click, or timed according to the number keys 1 - 9 each representing the number of seconds the display should be switched off for?
A fairly simple Applescript can do this for you. There are a number of easy to use Applescript tutorial texts and many sites on the web with online tutorials as well. Apple stores have classes sometimes on this topic. Alternatively, maybe you can find someone to write the script for you.
Applescript is a very powerful yet user-friendly programming environment (I have five different Applescripts running right now). You may want to ask the question at macintouch.com and macosxhints.com (check their database of scripts first) because a number of Applescript "gurus" frequent those sites.
HTH and please let us know what happens. Thanks.
Thanks for the reply. The applescript part of the problem is the easy bit. My searching the internet just didn't reveal a solution to this particular problem, and so I wondered if it was possible, but as you seem confident, I'll have another look.
