I have 2 rescue studs 2yrs old worst one has 0 testicles down, the other has one, is this normal?
Hit Control+F7, this will toggle the ability to tab between buttons. When you tab to the button you want to select, hit the space bar to select it (Return key will select the default, not the button you tabbed to). Arrow keys can be used just like the tab key. You can also go to System Preferences, Keyboard Mouse, Keyboard Shortcuts. At the bottom, you will see 2 check boxes under Full Keyboard access, choose All Controls. This is the same as hitting Control+F7.
Anything is possible, but not very practical. Antilock brakes have many components and need to be tuned for your vehicle.
