Smaller increment in scaleing

I need to have a smaller increment in scaling than the default .01. I’ve read that using shift in conjunction with the increment arrow will change it’s value, but that does not seem to work. Is there a way of changing the increment.
I know I can type in an exact value, but that is very time consuming.

The shift key dont work with the < > Buttons, only if you drag the value with the mouse.
And i agree that should be fixed to be more consistent.
