Markdown Cheatsheet

You are halfway through a README, you need a table, and you freeze. Was it pipes with colons? How many dashes in the separator row? Markdown is simple enough that nobody ever bothers to learn all of it, and the parts you touch once a month, like footnotes, checklists and escaping an asterisk, are exactly the ones that vanish when you need them.

The page lists twenty constructs, each with the literal snippet on one side and a short label for what it does on the other. The search box filters both sides at once, so typing table finds it by label and typing a backtick finds it by symbol. One honest caveat: despite what the tool description suggests, there is no rendered preview here. You get raw syntax and a label, not the formatted result.

Much of the list is GitHub Flavored Markdown rather than plain CommonMark. Strikethrough, checklists, tables and footnotes work on GitHub, GitLab and Obsidian, but an older parser or a restricted comment box may print them as literal text. When the destination is unfamiliar, test one item before rewriting a whole document. The list is static and lives entirely in the browser; the filter queries nothing.
