If you use a custom file extension for your Markdown files—like .md, or .markdown, or whatever—instead of .txt, Windows will only index their filename, not their content even though they are still text files. So, any Windows search will completely ignore their content.
It’s silly, but the good news is that it’s easy to change this by telling Windows that your .md or .markdown files are to be treated like standard text files.
Press the Windows key and start typing “Indexing” until it suggests “Indexing option”. Open it.
A small old looking window appears. Click on Advanced, in the bottom:
Another window opens, click its File Types tab to see the list of all the file extensions used on your PC. Scroll this long list until you find your own Markdown file extension (md, in my case):
Click your extension once. Then look at the bottom of the window and check Index Properties and File Contents.
Done. Windows will need a few moments to rebuild its index but now the content of your Markdown files will be searchable too. Yeah.
As a writer, Dictionary is one of my favorite apps under macOS. It’s also one of the most underestimated.
It includes English, French, German dictionaries, and a few others. It comes with an integrated French-English dictionary, and others I don’t use. You can use it as a front-end to search Wikipedia. Add to that a tight integration to macOS—you can invoke it from almost any app containing text, with a gesture or a right-click on a word—it’s hard not to love this app.
