From argument to object - 1225 entries

Reconstruct the actual output from my unit test tool report - 95 entries

When a test fails, my unit test tool reports differences between the actual output and the expected output as follow: - line in the expected output but missing in the actual output are prefixed with a dash - unexpected lines in the actual output are prefixed with a plus sign - comments added by the unit test tool are prefixed with a question mark - common lines are showed `as-is` (well, almost;) From that "diff" format, I would like to reconstruct the actual output.

comment and uncomment code inline - 947 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.

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 :)
