Shortcut Button on iPhone: Every Way to Trigger a Shortcut

A shortcut you cannot reach is a shortcut you will not use.

I have watched this play out with my own users more times than I can count: someone installs a Shortcut, runs it once from inside the Shortcuts app, thinks “that was faster than the website”, and then never opens it again, because opening the Shortcuts app to run a shortcut is more effort than the thing it saved them.

The fix is putting a button somewhere your thumb already goes. iOS gives you seven or eight places to do that, they are all free, and most people know about one of them. Here is the whole list, with the honest case for each.

1. The share sheet, which is the right answer more often than people think

If your shortcut acts on something, a file, a photo, a link, a bit of text, the share sheet is where it belongs. You are already in the app holding the thing. You tap Share, you tap the shortcut, it acts on what you had. No app switching, no copying and pasting, no losing your place.

To switch it on, open the Shortcuts app, open the shortcut’s details, and turn on the option to show it in the share sheet.

Then in any share sheet, scroll the row of app icons all the way to the right, tap More, and drag the shortcut up the list so it stops hiding behind fourteen apps you never use. That reordering step is the one people skip and it is the one that decides whether you use the thing.

This is why Grabio is built share sheet first. Every job it does starts from a file or a link you are already looking at, so any other trigger would mean going and fetching the file yourself. The reasoning is part of how Grabio works.

2. A Home Screen icon

The most literal reading of “shortcut button”. Open the Shortcuts app, open the shortcut’s details, use the share option, and choose Add to Home Screen. iOS lets you pick the name and the icon, so you can make it look like anything you want.

The menu names here have moved around between iOS releases, so if the wording does not match exactly, look for the share icon inside the shortcut’s own detail screen rather than the one in the shortcut list.

Worth knowing: a Home Screen shortcut icon opens the Shortcuts app for a moment before it runs. On modern hardware this is a flash. It is still not instant, and it is why the Action button beats it for anything you fire dozens of times a day.

3. The Action button

The dedicated button on the left edge, above the volume keys. It is on the iPhone 15 Pro models, on iPhone 16 and later, and on the 16e and 17e. By default it toggles Silent mode, and almost nobody needs a physical button for that.

Go to Settings, then Action Button, and swipe through the options until you reach Shortcut. Pick your shortcut and you now have a hardware button that runs it, including from the Lock Screen without unlocking in many cases.

You get exactly one Action button, which sounds limiting until you point it at a shortcut whose first step is a menu. Then one button gives you six or eight options. That structure, a Choose from Menu action branching into several tools, is how Grabio fits a whole toolbox behind a single entry point.

4. Back Tap, the one nobody has enabled

This has been in iOS since iOS 14 and hardly anyone uses it. Go to Settings, Accessibility, Touch, then scroll to the bottom for Back Tap. You can assign a shortcut to a double tap or a triple tap on the back of the phone.

It works on iPhone 8 and later, and it does work through most cases. Two caveats from using it daily: it fires by accident occasionally when you put the phone down hard, so do not assign anything destructive to it, and triple tap is noticeably more reliable against false positives than double tap.

Best used for something you want while the phone is in your hand and the screen is showing something else. A recording toggle, a Focus switch, a torch.

5. Control Centre

Control Centre became properly customisable in iOS 18 and remains so in iOS 26. Swipe down from the top right corner, press and hold on an empty part of the screen to enter edit mode, tap to add a control, and search the gallery for the Shortcuts entry.

You can give a shortcut control different sizes and put it on its own Control Centre page, which is genuinely useful if you have a group of related shortcuts. A whole page of file tools, one swipe away, is a reasonable setup.

6. The Lock Screen

Two options here. The two buttons at the bottom corners of the Lock Screen, torch and camera by default, can be swapped for something else including a shortcut, by long pressing the Lock Screen, tapping Customise, choosing the Lock Screen, and tapping either button. There are also Lock Screen widgets in the row under the clock, and the Shortcuts app provides widgets for those.

The Lock Screen is the fastest trigger on the phone, since it needs no unlock and no app. It is also the most public, so think about whether you want that particular shortcut runnable by anyone holding your phone.

7. A Home Screen widget

The Shortcuts widget comes in a few sizes and holds several shortcuts at once, laid out as a grid of tiles. One tap runs one of them, and unlike a Home Screen icon it shows you the whole set without a folder.

Good for a themed group. A row of four file tools, or four Focus switches, in one widget on your second Home Screen page.

8. Siri, and no button at all

Any shortcut can be run by saying its name to Siri, which is a free trigger you get without configuring anything. Rename the shortcut to something you can say without feeling silly and it works better.

And the real answer for a whole category of tasks is no trigger whatsoever. The Automation tab in the Shortcuts app runs things on a time of day, on arriving or leaving a place, on joining a Wi-Fi network, on connecting a charger, on opening an app, or on a Focus switching.

If a shortcut should always run in a given situation, do not give it a button. Give it a trigger and forget it.

Which one to actually pick

A rough rule that has held up for me:

• Acts on a file, photo or link: share sheet, every time.
• The single thing you run most: Action button.
• Needed while the screen is busy: Back Tap.
• A group of related tools: Control Centre page or a Home Screen widget.
• Needed fast, from cold, with no unlock: Lock Screen button.
• Should happen without you: an automation, not a button.

Worth putting behind one of those buttons

If you want something useful to test this with, Grabio is a free Apple Shortcut with no App Store install and no account.

It sits in the share sheet and handles the file jobs iOS makes awkward: converting HEIC to JPG so an Android friend can open your photo, shrinking a photo under an upload form’s limit, pulling the audio out of a video, and generating a QR code from any link you share to it.

All of those run on your phone using Apple’s own actions, so it works in airplane mode.

Get the Shortcut, then spend two minutes deciding which button to put it behind. That second step is the one that decides whether you still have it next month.

Shortcut button on iPhone: FAQ

How do I put a shortcut on my Home Screen?

Open the Shortcuts app, open the shortcut’s own detail screen, use the share option there, and choose Add to Home Screen. You can set a custom name and icon before adding it. The exact menu wording has shifted between iOS versions, so look for the share icon inside the shortcut rather than in the list.

Which iPhones have an Action button?

The iPhone 15 Pro models, iPhone 16 and later, and the iPhone 16e and 17e. Older models without it have a Ring and Silent switch in the same position instead, and can use Back Tap or a Home Screen icon for the same purpose.

Can one button run more than one shortcut?

Not directly, and there is a good workaround. Point the button at a shortcut whose first action is Choose from Menu, then branch into as many tools as you like. One button, one menu, several outcomes.

Why is my shortcut not showing in the share sheet?

Two reasons, usually. Either the share sheet option is switched off in the shortcut’s details, or it is switched on and buried. Scroll the row of app icons in any share sheet all the way right, tap More, then drag the shortcut up the list and switch it on.

Does Back Tap work with a case on?

Usually yes, through most normal cases. Very thick or heavily armoured cases can make it unreliable. Triple tap is more resistant to accidental triggering than double tap, which matters if you assign anything you would not want firing when you set the phone down.

Can a shortcut run from the Lock Screen without unlocking?

Often yes, depending on what the shortcut does. Shortcuts assigned to the Lock Screen buttons or to the Action button can run without unlocking, though anything that needs access to protected data will still ask for Face ID first.
