Assistive Technologies Icon... turn it off?
 

I used the Assistive Technologies on screen keyboard because hotplug was not working and I could only use my bluetooth mouse. Now, even after disabling Assistive Technologies, the icon still appears in the apps toolbar, next to my network connection status icon and battery status icon, also next to the clock and date.

Any ideas on how to keep this from turning on?

I am guessing you are using the Gnome desktop.

Try pointing the mouse at the icon, right-clicking, and looking for "remove from panel" or "remove from toolbar" in the pop-up menu.

Yeah, I thought it would be that easy too. There is no right click menu.
