I’ve used Alt+Double click when I wanna quick zoom…
but now it doesn’t work, so I just use ‘F’ Key for zoom ,
I think I have set about this key last time. .
I wanna recover this hot key, where can I set it up !?
In Z4R2 it is set by default to ALT+SHIFT Click.
You may choose your preferred method in ‘preferences/Edit/Enable Auto Center’ slider.
