Song Transcription Oops - 183 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 :)

Don't know what this is - 1822 entries

Replace contents of brackets with matching number of spaces. Don't ask what the format's supposed to be.

comment and uncomment code inline - 892 entries

It's very useful to be able to comment out a block of code in a quick edit. And likewise to uncomment the code. This operation often involves multi-line stanzas and even large blocks. 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.
