Is it possible to horizontally scroll with a trackpad?

I swear this was working before, but now the only way to scroll horizontally appears to be the arrow keys (which is not entirely obvious). Is there a way to enable horizontal scrolling with the trackpad?

Edit: it appears to work part of the time. Not sure what the problem is. I'm using Chrome 39.0.2171.71 (64-bit) on Mac currently.

It would be useful to have a survey of where it works and where it doesn't. We have tried jQuery plugins that enable more touch features but they interfere with others. This is mostly a task of assembling encodings that the industry itself can't keep straight.
