Rebinding the Click To Move feature

[Malakahh]

I've recently purchased a Surface Pro tablet, and discovered that it is actually able to run WoW fairly well (on low settings, ofc).

As you might imagine, movement controls are a little awkward and so I've created a small addon able to control the camera, not unlike the thumbsticks on gamepads, which works nicely. Now I'm on to the actual movement.

As the ingame MovePad isn't able to turn the character, I turned to the Click To Move feature. Click To Move is currently bound to the right mouse button, which isn't ideal, as a tap on the screen is a left click. Having failed to find a rebind option for this, I'm now turning to see if an addon could help in any way, and if the good folks here could shed some light on that.

This could possibly achieved by using something like AutoHotKey, however, I'd really prefer doing this using the ingame interface, as I'm not convinced software like AutoHotKey is condoned by Blizzard.
