Hi,

I've created some Keyboard shortcuts for line widths I use most with autohotkey.

For example .3pt, .7pt, 1pt, 1.5pt, 2pt, etc..

It's somewhat quirky because it simulate button pressing but it works.
I have integrated very quickly into my workflow.

If ever you're interested I could share the script.

I have also thought of a script that would + or - .5pt per keystroke but I'm afraid I'm not that good!
