I'm new to ID but just wanted to ask if it is at all possible to change the values of, for instance, font size by clicking into the font size field and using the mouse wheel (up and down) to increase or decrease the size.
It doesn't seem to do this so my guess is that it ID CS6 doesn't support this kind of activity?
Is this just how it is?
No Indesign doesn't have this functionality , If you are new start using both hand then only you will speed up your work.
Knowing shortcut and using them is important in Indesign.
