tablet pro

3 questions.

1. On the program I'm using(Ableton Live) the left, right, up, and down keys are registering as numbers. Its like its using the number pad arrows instead. Is there away to have it use the actual keyboard arrows?

2. Is there a way to have keys repeat when being held down. Like in ableton to zoom in, you press the "+" button. Is there a way to when I hold "+" for the action to repeat so it will KEEP zooming in till I release the button?

3. Is the a way to autohide when Cortana is active? When I hit the start button, my artist pad (docked to the left) disappears. But when I hit Cortana, the menu is behind my artist pad.

Any help would be highly appreciated. Thanks!!!!
