KEYBOARD SHORT-CUTS FOR ALL!
A roll your own universal keyboard short cut for particular features of any existing non-keyboard mapped applications. (menu's, buttons,series of swipe actions etc)
So that every app that has no keyboard support may be mapped with keyboard shortcuts, within the context of that app running.
The keyboard app would snap to the existing app,
and intercept all keystrokes when the app was in focus,
and supply the equivalent swipe feature as if the app received that instruction from the touch screen.
Some innovative means: for a reader type app , map the space bar to a move down of so many lines (font size dependent) to mimic a page down).
For games to map actions to keystrokes (ie fire or whatever the spacebar)....giving your games joystick like controls, even with the capacitive touch functionality(as a substitute for a joystick?
A possible method of learning is set the keystroke, and record the actions by your gestures, until you complete the 'macro' ...possibly include <pause for input> type constructs withing these keystroke shortcuts.
