Illustrator for a one-handed person. Windows 7

We need to provide Adobe Illustrator training for a person, who can work with only his left hand. We are looking for solutions for making traditional "two-handed" operations (pressing several keys and/or pressing a key + doing smth with a mouse) with one hand (in Windows 7). Sumultaneous pressing of several keys can be perfectly emulated with "sticky keys" feature.

But I can't find a way to emulate "keyboard key + mouse" operations. For example, to make corner Bezier point "on the fly" when drawing with the Pen tool, one must drag in one direction and (without releasing the mouse button) Alt-drag in another direction. Is it possible to do with one hand?

Is there a way to press some key(s) before the corner point to inform Illustrator to regard first drag as "simple drag" and the second drag as "Alt-drag as if without releasing the mouse button"?

Can the "temporary pressing Alt key" be "hanged over" to right mouse button or to the middle mouse button (wheel)? Is it possible to do with Wacom pen tablet? Are there any foot pedals or anything similar so that we could assign the Alt/Shift/Ctrl functions to them?

Thanks for any ideas in advance
