Numeric button remapping, for faster typing

Feature request mail.

I thought it would be neat if the following key bindings were active while entering answers:
` -> -
1 -> a
2 -> b
3 -> c
etc...
This way you don't need to move your left hand at all and your right hand is free to turn pages :)

Thoughts:

It has actually been disrequested by others.

The risk of not spotting missclicks is much higher when using buttons which are close to each other, yet they all produce 'valid' answers.
e.g. a missclick of "v" instead of "b" will be caught.

If implemented, it should not be enabled by default, it should come with a warning -- perhaps encouraging the use of the sounds.
