Feature request: Horizontal scrolling

[thibaultmol]

Hi,

I recently realized that being able to move the slippy map using the horizontal scrollwheel that a lot of mice have these days, could be useful.
I imagine using it like this:

Horizontal scrolling: moves the map horizontally.
SHIFT + Horizontal scrolling: moves the map vertically

(right now horizontal scrolling doesn't do anything in the editor it seems)

Cheers,
Thibault

@thibaultmol Hmm scroll-to-pan already works on many devices. Perhaps this is #6598?

Just tried it on my windows pc with chrome stable. Also doesn't work.
I don't think they're related though.
Just so we're on the same page, I'm talking about these horizontal scroll wheels:

Example code:
https://jsfiddle.net/alecazam/my6gntrr/
See video of that jsfiddle and me scrolling on the horizontal scrollwheel: https://photos.app.goo.gl/ZXNx18W3pKhagG9dA

It can be implemented using 'wheelDeltaX', see this documentation: https://developer.mozilla.org/en-US/docs/Web/API/Element/mousewheel_event

I tried this suggestion out today (in the issue-7134-horizontal-scrollwheel branch), and it works in principle.
But to be honest, while trying it out, I found it not very useful in practical usage. It's pretty rare that one only wants to pan horizontally or vertically and while mapping long linear features (such as a stream for example) click-dragging is more useful since it does not modify the relative position of the mouse pointer to the already-drawn part of the feature.

It also doesn't help that the regular "Y" scroll wheel has a different functionality already which means that in order to navigate the map using the horizontal "X" scroll wheel alone requires the use of modifier keys (which feels also quite clumsy).

@thibaultmol: Did you have a specific use case in mind for panning via the horizontal scroll wheel, which I'm not seeing at the moment?

Otherwise, I think there are better ways to utilize the horizontal scroll wheel in iD, for example to cycle through different background layers, cycle through the nodes of a way and/or to nudge/scale the position of existing features.

I had a while where I accidentally moved objects while panning by just dragging.

Problem is, I don't know where my MX Master is, so i can't actually test this branch atm.
What do you mean with Y scrollilng btw?

(If you think it's not a good addition to iD, then I guess you could close the issue for now (I can always reopen it when I get my hands on a mouse again with and extra scroll wheel like that... I'm sure the MX Master is lying around here somehwere... we'll find it.. XD)
