(keys? I'm not sure how the <End> key is handled)

Here the <End> is literally the "End" key.

i <End>_:s/./ |\0|\r/g i/___\ VvVggxo /_\ 

Unprintables so:

i <End>_^[:s/./ |\0|\r/g i/___\ VvV^[ggxo /_\^[ 

I'm a little sad that I couldn't get to @DrMcMoylex V answer byte count, but that's the point of V isn't it?
