Thanks to this tweet today I learned how to change the font in Slack. And to be honest, I’m more than happy to discovered this on a Friday because I’ve spent the last hour trying out ridiculous fonts just to realize it I didn’t know how to reset it.
If you’d like to try this out for yourself, just tap to do it / slackfont followed by the name of a font you have locally. Yes, / slackfont Comic Sans MS works. It does / slackfont Wingdings. You need to make sure that you enter what the font is named locally for you / slackfont Comic Sans will not work; It must be / slackfont Comic Sans MS. After some quick googling and frantic updating of the twitter thread, I found that to reset the default font, all you have to do is type something / slackfont and press Enter.
Here are a few screenshots of my favorites:
