Keyboard Touch Screen Actions
If the touchscreen action for a normal key is pressed (e.g. ‘a’) the area corresponding to the touchscreen action is copied from the lower case pressed image to provide a visual indication that it has been pressed and then it reverts to the lower case image. The letter (or word) in the touchscreen action is added to the text area that has focus.
