Laptops mostly have a touchpad for moving these days, below a rectangular keyboard which is mostly crammed into a space equal to or slightly smaller than the screen.

Annoyingly it's often necessary to 'stroke' the touchpad a few times to move the mouse cursor large distances on the screen.

Given that the screen and keyboard can be thought of as roughly the same dimensions (give or take a little aspect ratio adjustment) how about a system whereby pressing the laptop's mouse button in conjunction with a keyboard key takes the cursor quickly to a point relative to that on the screen?

Ie. press button plus '1' takes you to top left. Press button plus bottom right shift key takes mouse cursor to bottom right of screen.

This would make moving your mouse cursor large distances a lot faster and involve no extra hardware.

Combined with a little extra software you could make the cursor jump to the only viable destination in that area (like a 'Submit' button or something). There may be other enhancements too.

To avoid loosing your cursor on large jumps it might be best to use this with software that enlarges the cursor when moved then quickly shrinks it back to normal size.
