it is surely a easy answer but i can't find a way to change opacity by taping numbers on my Macbook Pro Retina (French version AZERTY).
I think the problem comes from the fact that i don't have a numeric keypad.
For instance, on the brush tool, if i enter 1 (by pressing shift+&), i change the flow to 10% and so on, but i didn't find a shortcut to change the opacity.
On the move tool, if i enter 1 (by pressing shift+&), the opacity of the active layer don't change.
I am nearly sure that the problem comes from the Macbook Pro Retina keyboard, so do i have to buy a additionnal numeric keypad ?
What version of photoshop are you using?
Is your version of photoshop also french?
Actually i don't think you should need the numeric keypad.
Maybe your right about needing the numeric keypad after all.
A quick test in cs6 seems to indicate that.
You might also ask over on the french forum:
