Unsemantic linewrapping - 928 entries

[Inspired by a blog post I read: https://scott.mn/2014/02/21/semantic_linewrapping/. Text adapted.] Sometimes when editing a Markdown file, I wrap the lines semantically. Instead of inserting a newline at 70 columns (or whatever), or making paragraphs one long line, I put in newlines at a point that seems logical to me. This may seem silly, but it produces better diffs. Semantic linewrapping also makes editing snappier. I can delete, edit or insert sentences easily using linewise operations. Code-oriented text editors like Vim and [REDACTED] are really good at this kind of manipulation. Editing text that hasn't been wrapped semantically is a pain, though:

comment and uncomment code inline - 1122 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 - 243 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 :)
