Switch editing modes manually
Editorial has Markdown and Plain Text modes. How do I switch them without changing a file's extension?
Specifically I sometimes want .txt displayed in monospace, sometimes proportional.
It doesn't really have markdown and plain text modes; it always syntax-highlights markdown that you enter, even in a .txt file. The only difference is that you can only see in the preview files that have markdown extensions.
To change the font in a .txt file (monospace etc), the only way I know is to change it in Settings.
