Using Text Transformations and Building Your Own On a Mac
You can use default text transformations on your Mac to convert text to upper or lower case, or to capitalize every word. However, it is better to use styling in Pages. You can also create your own custom text transformation with Shortcuts.
I see Gary is still promoting the clunky Short Cuts app in this tutorial on "Using Transformations". The first part of the tutorial was excellent in its simplicity and clarity. The second half had me in fits of laughter at the contortions forced by the Short Cuts app to alter a few letters.
Barry: Shortcuts is part of macOS now. Not sure why you think I'm "promoting" anything here. Is it perfect, no. But I'm showing some interesting ways to use it. If you don't want to take advantage of parts of macOS that's fine. You don't need to use it all. Not sure why the negative comment here though.
According to a WWDC 21 presentation, Shortcuts is the future of Mac automation. In the future
Apple will probably add more intents/actions to its Apps as well as third party App developers. Shortcuts is the only automation App that runs on both macOS and IOS.
Thanks Gary. I found it helpful! Clarified distinctions and possibilities I was only vaguely aware of.
