Hello, I was wondering if there was a way to enter control characters in a text editor for mac os x 10.6? Like if I wanted to enter control a? I tried holding down the control key and pressing the letter a key in text edit and text wrangler on my mac with no luck. I did see the ^ symbol above the 6 key and was able to write ^a but I don't know if this is the same thing as the control character? I want to send commands to a serial device, any help would be appreciated.
