Increment ems/rems by 0.1 in firebug or chrome dev tools?

Question

Trying out the EM Koolade but getting frustrated while working in firebug or chrome dev tools as the size jumps are too big.

Is there a way to configure these tools to increment rems or ems by 0.1 instead of 1 on the fly?

Answer 1

Hold ALT and press the up arrow. You can also hold ALT and scroll up with a mouse or its equivalent with a touchpad (Just make sure your cursor is on the size).
