FWIW Somebody suggested, and I use
noremap ; : And Tony responded (in part): Your example of a semicolon? The "search for the next f/F/t/T search on the line in the same direction as before" command. I used to use ; for this fairly often, especially with vi, but since I mapped it to colon I *love* it, and regret not having done it years ago. There's so much available in command mode with Vim; it would have been best to have adopted this map when I started with Vim. I suspect that on Bill Joy's original keyboard a colon was not a shifted key press. Friendly regards, John Little
