Make a text file. Select the name (click, short pause, then click again). Add “.markdown” (dot but no quotes) to the end. It’s now a Markdown document.
I like my own Path Finder-style renaming script that I’ve assigned to command-shift-R so that I can select a document or group and pop open a dialog to easily change the name.
