As you undoubtedly know, TYPING IN ALL CAPS is considered shouting on the Internet. Does it bug you when you accidentally tap the Caps Lock key and start writing in uppercase? MacOS lets you disable or remap it. In System Preferences > Keyboard > Keyboard, click the Modifier Keys button. In the dialog that appears, choose No Action (or another key) from the pop-up menu next to Caps Lock. Click OK and you’re free from accidental capitalizations.
