Little tip that can save a ton of time for when typing using the emulator. The on-screen keyboard will jump up by default and allow you to use the mouse to click on the keys you are after. However, by default, it will not allow you to use your computer's keyboard to input text.
A very counter-intuitive way around this, is when the on-screen keyboard is shown on the emulator, simply hit the PAGE UP button on your machine's keyboard. This will dismiss the keyboard and let you type at full speed.
And yes, PAGE DOWN will allow you to restore the on-screen keyboard.
