Hello every one, this is my first post, so hi. I recently discovered the speech capabilities of my 20 inch iMac (OSX 10.5.6, 2.4 Ghz, 4GB RAM). i have had a lot of fun showing off to my Windows using friends but i noticed (or overlooked) it does not have a "go to sleep" command. My question is, if OSX has a sleep command what is it, or if it does not, can i make one? ( I have no experience with coding of any type and I am relatively new to Macs. I would appreciate so help, thanks!
