Hey everyone, quick question. Tomorrow I'm going to be presenting a self-standing Keynote (Mac version of PowerPoint) presentation at school, and my Macbook will be sitting on a table, not always under my own supervision. I would like to figure out a way to lock the keyboard and make it temporarily disabled, because all that the other students will need to do is click and move the mouse. Is there a way to do this? I just don't want people messing around quitting the program, inverting the screen colors, etc. If not, do you have any suggestions for other things I could do to keep people from screwing around on my laptop? Much appreciated. Ben
