The wheel will have to be careful.
Multi-touch in the browser works with ctrl + wheel.

Since ctrl + wheel also has a zoom function in the browser, it looks like it should be handled with preventDefault.
In Axes, preventDefault is already applied for ctrl + wheel, can be there any additional processing needed?

The action of inputKey is the same as or.
If so, does it also support and behavior?

Currently this does not support and behavior. I designed this as or for the following reasons.
- Certain input devices do not have an Alt key, so it need a replacement.
- A similar option
inputButtonis implemented asorand both options are array, it seems better to work consistently withor.

Isn't every event valid when there're no items in inputKey and inputButton in this case?

Since array is type of object, an empty Array is conversed to true and !inputButton is conversed to false.
The reason to check !inputButton here is that inputButton is optional like in the case of a pinch gesture where there is no inputButton option.
But for what you said, it seemed nice to add the case where inputButton is an empty array to the unit test, so I added it.

You should change the document, as it looks like ANY replaces this
Details
This adds
InputKeyoption that accepts input only when certain keys are pressed for thePanInputandWheelInput.Considering that some devices don't have an Alt key and use a meta key instead, I implemented
InputKeyoption to be an array of keys that allows input when any one of these is pressed.
