To me, “tap anywhere at the top to scroll to the beginning” is an amazing and underappreciated mobile gesture:

It not only provides an alternative to desktop‘s Home and ⌘↑ keys, but the student laps the teacher here; it’s actually better than every way to scroll to the top on desktop (do you like pressing ⌘↑? do you even have a Home key?), and it’s an icing on a cake of a regular flick to throw the page to the top already being pretty nice.

Tap to return to top is also distinctively mobile in that it allows you to tap just anywhere near the top edge that’s not already a tap target; as far as I can observe, traditional GUIs detest being imprecise in this way, always asking you to click on something specific (although window moving on macOS in the post-title-bar era is also starting to feel similar).

The iPhone gesture seemed to work so well that, over the years, more patterns started borrowing from it. In Bluesky and tons of other apps, you can tap on any tab with scrollable content a second time to scroll all the way to the top. (Again, something that’s hard to imagine on desktop, where you pretty much almost never think of clicking on an already-selected item.)

It’s not just the top, either. In Podcasts, tapping Home goes back to the left:

And in Photos, to the bottom:

To me, the whole “tap to return to the beginning” gesture universe feels ascended to be the core property of the interface. In that way, it is similar to scrolling, undo, copy/​paste, arrow keys moving the text cursor, and so on, all inducted to the National Register Of Historic Gestures.

Why? Because these gestures can only blossom if they work consistently, everywhere. You need to start trusting them so much they slide into your subconsciousness. Breaking the gesture in one place will make it less trustworthy in other places, too, ejecting it from motor memory back to the level of deliberate effort, and therefore making it a lot less usable. “Does this thing work here or not?” is a death knell of flow.

The fact that tapping on tabs is idempotent means there’s also no penalty; if you’re already at the beginning but are not sure, tapping it mindlessly won’t hurt or send you back somewhere else.

This is all great. And this is why I’m unhappy Safari started mucking with it.

Safari has tabs at the bottom – starting with two (regular set and “private” set), although you can add more. Above is a long list of site cards, with newest at the bottom. It’s exactly the same situation as in Photos, and yet tapping on either tab doesn’t restore the scroll position. Instead, it opens the settings dialog:

And, tapping around the buttons does nothing.

I would imagine Safari is a pretty important app used by many people, and so this feels like a bad place to introduce an inconsistency that could have a more serious consequences of un-teaching people about tap to scroll to top in the long run.

The funny thing is that the solution is already there: you can tap ··· in the upper left corner to get to the same functionality. The long press on the tab also opens the same menu.

Messing with a “tap to go back to the beginning” system gesture like this means to me the design team doesn’t fully share the understanding of the value of their own creation, or maybe that stewards of the gesture system are not vigilant… or perhaps the awareness is there, but the caretakers aren’t recognized, rewarded, or empowered enough.

It’s similar to the “no, thanks” example I shared before, a possible worrisome tragedy of the UX commons in the making if the respective teams do not change course. Because, wedging that sort of an exception in – even if you have a great set of reasons in the moment – creates a precedent. Inevitably, from my experience, the next team that will want to override scroll to top, or misuse “No, thanks,” will now require less of a justification.
