CTRL scroll zoom on Mavericks gone

Question

I used to be able to hold down CTRL and zoom by scrolling the mousewheel, but that is not longer possible on Mavericks.

I've searched around and found many people saying it's in System Preferences → Accessibility, typically accompanied by an image like this:

Unfortunately, that's not how my Accessibility window looks. All I get is this (and no, it's not under More Options):

Naturally, I tried searching in System Preferences, too:

Excitedly, I click Mouse, just to get disappointed:

There's nothing under Trackpad, either:

So what's wrong? Where did it go? Why does it show up on some Mavericks installations, but not mine? I have the newest version of Maverick (10.9, 13A603) made from a clean installation. Can it be because other people have upgraded from a previous version of OS X that had the feature?

Answer 1

Press ⌘ command+⌥ option+F5, then select Enable zoom scroll gestures.

Answer 2

OS X thinks that the mouse you are using doesn't have a scroll wheel.

Answer 3

I'm here years later after returning to my MacBook Air and finding this zoom feature missing. Type in "zoom" in System Preferences search and picked the "zoom to enlarge screen" option from the list and it took me right there!

Answer 4

I've just spent several hours on chat and phone to Apple support about this issue on a brand new iMac, with a clean Mavericks installation and a three year old Mac Mini with an upgraded Mavericks installation.

The common thread between the two machines (neither of which show this missing option) is that they both have, or used to have, the Microsoft Intellitype/Intellipoint drivers.

My iMac is having issues forgetting about these drivers on boot/wake from sleep/when the moon is half-full, and it seems like maybe they've interfered with the way Mavericks determined the scroll ability of the mouse.

I started setting up the iMac with an Apple wireless magic mouse, but reverting to that doesn't make the option appear in Accessibility either.

Apple are escalating this to an engineering team: if I get any answers, I'll post back.

You started on the correct screen but you have to go a step further and hit the OPTIONS button on the lower right of the preference panel. It should take you where you need to go.
