Before I contact p5p, I would like to hear your opinions for this proposal.
From time to time, I wonder why n doesn't jump map, grep, etc. I usually end up using c in those cases, but it's slower since I need to get the line number first. Therefore, I suggest that you try p5p, explain them grinder's comments about backwards compatibility and the idea of using N as an alternative.
BTW, maybe if it was possible to set n as an alias for N and let people decide whatever they like most would be the perfect solution. However, I'm not sure that aliasing (or redefining) commands is possible at all.
