copy 10 lines from the current position into buffer q, go to the start of function jnk, copy 5 lines into buffer w, jump to line 10, paste contents of q, contents of w, and contents of q sequentially one after the other:
"q10yy /jnk "w5yy 10G "qp "wp "qp
now, go to the start of the document and indent the next 20 lines by 10 spaces:
0G .,+20s:^: :
ok great, now find JUNK and replace 'a1' with 'A1' in the 15 lines that follow:
/JUNK .,+15s/a1/A1/g
probably not as efficient for multi-file refactoring, but for raw 'drag race' style text munging, everything is there, loaded in muscle memory, and under the home row of your keyboard so you don't have to lift your hands at all.
