Okay, this is probably specific to fewer than 1% of Chromebook or CloudReady users but without I/we will never be able to fully use Chromebook. Yes, there is Tap Drag but that doesn't work for me because most mouse pads don't recognize touch or pressure by a non-human finger. I have no movement from the neck down. I type using a mouthstick and can only tap one (1) key or mouse button at a time. At least sticky keys works but I need something like Windows has implemented into their OS.
Chromebook needs the ability to hold down the left mouse button for one to two seconds which will "lock" the button tricking the OS so it thinks the button is being held down. That would allow me to drag the mouse (I use a trackball) for my computer needs. This should be available in the Accessibility area under mouse menu.
In Mac I use Kensington's app to customize any button but Window's mouse drag option is much better and not limited to a specific brand of mouse.
Hopefully this can be incorporated into a future build. Other than that, I'M LOVING CHROMEBOOK + CLOUDREADY!!
