This article explains how to customize and use the iPhone Action button.
But, that’s far from the only thing it can do.
To customize the iPhone Action button, run with this:
TapSettings.
Apple Inc.
Swipe side to side to choose what you want to have happen when you long-press the Action button.
Examples of these choices include what Shortcut or Accessibility tool you want the Action button to launch.
Support for Shortcuts is the secret weapon here.
The Shortcuts app lets people create tiny scripts and apps to execute simple or complex, multi-step actions.
Any task Shortcuts can run can be triggered by one press on the Action button.
The possibilities are endless!

Needing to hold the button for an extra bit is designed to prevent accidental presses in pockets or purses.
Remember, the button can enter and exit a mode assigned to it.
