I am modeling by eye, which makes one-vector adjustments (e.g. typing just “,300-enter”, “,320-enter” until I like the result) a very valuable feature. Except, of course, for not being able to do so one-handed without looking at the keyboard each time, because the key I need is somewhere in letter land.
Sketchup seems to be underutilizing the number pad here.
Why not: + or - as a default alternative to comma?
I also see topics from European Sketchup users who use US keyboards having trouble with , in dimensions. A default alt would solve their diffuculty as well.
