ASCII Sniffer reads keystrokes from the keyboard and displays them and their ASCII values.
It also accepts a Text Paste, displaying the 1st character pasted and it's ASCII value. So a character can be located with "Key Caps" and Cut & Pasted into ASCII Sniffer.
ASCII Sniffer was written as a tool for other code I was writing. It was actually quicker to code this up in REALbasic than it was to find that damn ASCII chart that is still buried God knows where.
