A new feature in iOS 13 and iPadOS is the ability to have Shortcuts trigger automatically, at a certain time of day, when you launch an app, change a setting or move to a new location. You can use this to make Shortcuts much more useful. Take a look at two quick examples. The first simply forces the Calendar to jump to the current day every time you open it. The second will display a special Reminders list when you turn on Do Not Disturb, but only if there is at least one item in that list.
If you are new to Mac, learn how some of the most common keyboard shortcuts differ from what you may have learned to use on Windows. Realizing that the primary keyboard modifier on the Mac is Command, not Control, is the first step. But there are other differences and some shortcuts that are completely different.
