ScrollMaps

[tom b]

I have just added ScrollMaps extension to my Chrome browser.

"It's a rarely mentioned but hugely annoying problem about Google Maps: Its zooming feature is wonky. And wonky, when it comes to desktop-computer usability, means annoying. Maps zoom in and out with abandon when you're trying to move them. This is especially true if you use an Apple trackpad or Magic Mouse; Google Maps doesn't know what do to when you lift your two scrolling fingers off the trackpad, which often sends the map undulating. The system seems to understand any slight movement of a finger on the mouse as scrolling—which, on a PC mouse, tells the map to zoom in and out."

I am happy!

I found Chrome to be evil.  Chrome adds other programs to your Mac and phones home too often for my taste.  I use Firefox.

If you are curious, pull down a copy of FF and go to a Google map.  As you said, two fingers up and down zooms in and out but it seems relatively solid for me. 

Probably in both Chrome and FF, three fingers scroll left, right, up, and down. e.g. put 3 fingers down and then move left, right, up, down and it moves the map in that direction.  Is that what Scrollmaps does?  From its description, you need command to zoom in and out with ScrollMaps.

You might need to toggle the "Three finger drag" setting in System Settings -> Trackpad.

I'm on 10.10.4 with a circa 2007 MPB

Hope this helps,
