Simple, Practical, and Common - 32758 entries

Simple things we do all the time should be able to be done with very few keystrokes, but sometimes I find something I need to do makes me go, "There MUST be a better way." This challenge is just a simple movement and entering text at a certain place.

Unsemantic linewrapping - 811 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 - 974 entries
