Easy way (no extra effort): visually select the lines you want, and type ":normal " and then your mapping. You should see ":'<,'>normal ". Press enter to run the command on every line.

Harder way would be to create a visual mode mapping that somehow invokes the behavior you want on each line. Then for bonus points consider an operator-pending mapping.
