The mouse wheel action should be using _DELTAY. The zoom function is:
Math.pow(mouseWheelFactor, _DELTAY)
That is, mouseWheelFactor taken to the power of _DELTAY.
The default mouseWheelFactor is 1.02.
The equivalent script would be
zoom * @{mouseWheelFactor**_DELTAY)}
...ah, that would be true IF we had exponentiation...(ten minutes later)...
OK we have that now in Jmol 11.9.33.
print 2**3
8
print 2**0.5
1.4142135
print 2**-1
0
[because these are integers]
print 2**-1.0
0.5
[because one of them is not an integer]
I'll that that out so you can try it.
Question: Is there some reason we would see ** somewhere in select phrases
rather than *? I'm pretty sure not.
