Custom autocompletes/corrects. Just figure out a non-word (i.e. something that you wouldn’t want to use without autocorrecting) that’s easy to remember and set it up frequently used snippets of text. Some examples:

• meetnow - my zoom meeting link
• booktime - a link to my calendly
• frequent sentences or blurbs I use in emails (e.g. thanks so much, let me know if i can help with anything else sorta stuff)
• nicknames for different frequently used hex codes
• galert/yalert/redalert populate a styled HTML snippet to make a green, yellow, or red div that I can then just pop my content into
• lots of other little HTML snippets like that
• group nicknames to populate a list of email addresses (like an Outlook contacts group but you can use it outside of Outlook)

Anyway there are a ton of things I use it for, those are just a few examples. Saves me a lot of time.

You can do this on Macs at a system level, on Windows you can do it on some programs but it seems to have to be set up on each one which is worthless.
