Sure! ;-)

Yes, I have tested this - it works fine for me

Both CTRL+mousewheel and SHIF+mousewheel work fine for me!
(Apart from the fact that the point over which the mouse
pointer currently is not kept fixed, my first remark in #8 ...)

So because it works for me, but not for you,
this must then be the reason for the confusion?

I am talking about something differnt, namely
the sequence of zoom values which is obtained when
using CTRL + mousewheel ...

OK, then it seems easier to implement (no need to care about
a stored list).

Best, Arnd
