Writing a tiny undo/redo stack in JavaScript

It's very nice, but it doesn't do system undo. You can shake iPhones to get an Undo/Redo dialog, for example.

So you can probably trap Meta-Z but some people use menus or the other affordances.

Well, hooking into system undo is tricky as there still seems to be no native web platform thing for that. I see all kinds of things like https://github.com/samthor/undoer but the article was about the foundation, rather than the integration. For what I am doing, shortcuts + clickable buttons on screen will do the job.

If you're interested, [plug] here is my technique, just a page of script.

When are they gonna add a proper UI for this? I look like a moron using the phone this way, and shaking only works to trigger the undo about half the time.

Edit: thank you!

Man I get gestures have been embraced by the community, but this is emphatically not what I meant. The only gesture that makes sense to me is pinch-to-zoom and maybe swiping on cards that appear to be floating.

There's no way to discover this functionality outside of googling documentation and it often doesn't work with one hand.

There is another that is fairly intuitive for a Mac person: tap-and-hold to get a contextual menu. Shame they have hidden it under some kind of "haptic feedback" thingamagig.

The ipad also has an icon above its keyboard. Whatever lack of obvious interaction is available on the phone seems intentional.

Cynically, I think you'd just look like even more of a fool shaking an ipad and this is the only reason they approved such a button.

Half the time? More like 10% of the time.

Sometimes I think I have to use a paint can shaker on a 5-minute cycle just to trigger it.

TIL this is why that modal has popped up at seemingly random times.

Very useful, if you know how to summon it!

Around 2018, the ultra buggy Matrix messenger had a onShakeListener that triggered a dialog "It seems you are frustrated. Do you want to raise a bug report?"

Element's crash reporting system is still called 'rageshake' today, and you can enable the shake-to-report function in dev settings.
