Long prime list - filter version - 19 entries

I've used the maximum input/diff/output size allowed by vimgolf to get a list of integers up to 1460 separated by newlines, and your goal is to only keep the lines containing primes. There are 232 of them I hope some of you will golf vimscript itself to create some function to run as a primality check for each line, which is a good exercise if you haven't done much vimscript yet! You're invited to also try copy-pasting and doing other non-smart text manipulation. Even more interesting would be to see a solution that uses text manipulation to do the filtering! Whether you use vimscript, normal-mode primality checks, or text manipulation, as long as the end result is valid, your answer will be valid! Let's see which method does better here. Best of luck!

Song Transcription Oops - 197 entries

When transcribing vocal music to Canjo Tab you can start by finding the lowest note and assigning that to zero and working your way up from there. However, without fail, I tend to miscount the notes and when I am near done I find a lower note. I mark this with a "z". This means I have to increase all the previous ones by 1. just a sting of numbers :)

With just line-wise navigation and insert mode this would cost you about 4 keystrokes per line. Master this hole of VimGolf and you'll quickly drop your key count in day to day Vim as well.
