cheers :) for line counting - indeed a good point and clearly required for the examples - After time, eyballing this becomes a skill. For things that fit on a screen (~50 lines or so, give or take) I'm usually correct 1st time or within a few lines. I can check quickly by moving the cursor (20j to go down 20, 20k to go back, repeat if necessary to get the line count) also as others have pointed out, I might not be doing the best/optimal thing for some of these, just some examples of how I do things that popped in my head :)
