Full Keyboard Access
In Settings, Accessibility, Keyboard, there is a pretty nice feature called Full Keyboard Access. I have a problem with it. When I go to a type-in box, like this very type-in box, the first time I press the space bar, the keyboard goes into control mode and out of input mode. After typing the first space character, I can no longer input text, text such as this question. In order to even type this question, I had to go to settings and turn off "Full Keyboard Access," and that's a hassle. Is there some quick way to turn FKA off when I want to input text, and turn it back on when I want to control the iPad? Or do I completely misunderstand how to use FKA?
