Thanks.

Does this mean the middle button can be added as in my example script so that
it exists in between the left and right button?

The advantage is that you can use it with your thumb and using your index
finger you can make a selection or manipulate an object in another way by
sliding on the touchpad.

If it is going to be only an emulated on, where you have to touch both the left
and right button at the same time, this will be impractical for two reasons.
First the touch on the same time is not always synced by the users fingers,
posing a risk for unwanted other actions. Secondly, when two fingers need to be
used for touching two buttons on the same time, using the touchpad with a third
finger is not easy at all.

So in general to offer the user the choice, I would recommend these functions
regarding third mouse button pressed down for making selections:
- none at all
- software emulated by pressing left and right simultaneously
- software defined in between left and right button (my preference)
