That seems reasonable. So in summary, ESC 1 ^L gives a clean refresh of the command line when you're at a shell prompt, and ^R prints the contents of your typeahead buffer when you're not. I think that's what the OP /really/ wants. I can see no point in tying the ^R refresh to the Backspace key: if you rubout four characters, why would you want four refreshes? Perhaps, in some way, the OP hasn't got rprnt = ^R listed in their $ stty -a output, but that's beyond my knowledge. Cheers, David.
