I have Windows 8.1 (‘with Bing’) on a minicomputer used only for streaming. I control the computer from the couch with a wireless keyboard/mouse pad. Obviously I don’t have a touch screen with this configuration. To avoid excessive mouse movements, I use keyboard shortcuts where practicable. I would like to keep this set-up but it is causing some problems I can’t work around and I am wondering if anyone else might have some creative solutions:

1. Scrolling is a big hassle. I can scroll up and down with the arrow key, but I can’t go past the end of the visible screen area. To do that I have to steer the mouse cursor to the miniscule scroll bar at the far right of the screen and shift the viewable area that way. The mouse pad only has left and right keys and Control Panel offers no possibilities for emulating the scroll button. How can I solve this?

2. Mouse keys. Is there a way to jump the mouse cursor around the screen, from far left to far right, top/bottom, middle of screen?

3. The computer and keyboard provide no function for toggling wi-fi/airplane mode. Instead, I have to right-click the shortcut I made to Network properties, then click connect/disconnect to bring up the settings panel on the right side of the screen, then mouse to Airplane mode and click that, then mouse back to whatever I was doing. Is there a better way to do this?
