Thank you for the information.

I've got a Mac Magic Trackpad 2  and a Magic Mouse 2. I am learning to 
use them in JOSM. While doing it I discovered already quite useful 
things like keyboard shortcut - "8" returning to a previous zoom, moving 
a layer and to zoom with keyboard shortcuts, which I assigned to 
selected keys.

The issue is that the zoom both with the magic trackpad and with the 
magic mouse is a bit too fast and kind of volatile in JOSM. I read in a 
wiki that it is better to use a mouse with a physical wheel, however I 
would like to see if there are some settings which I could adjust to 
make it work well. Sometimes I cannot use a mouse with a wheel, only an 
inbuilt trackpad on a Mac notebook, which has got about the same 
functionality as Magic Trackpad 2.

Since there is no complete description of advanced preferences I will 
try either reverse-engineer their meaning by changing values and see 
what happens or have a look at the source code.

Best regards,

Oleksiy
