Does anyone know if there is either a keyboard shortcut or script available in order increase and decrease stroke width in Illustrator? I would love to be able to just hit Option + + or - or something of that nature with an object selected, but I have yet to find a solution on the internet.
I had to make some Actions to do it.
Before starting recording, fill the path with a pattern(this is necessary just to record the action). This is important to enable the Transform objects in the Scale panel.
Create I new action.
Select the Stroked object, press S , Enter and change the scale by 90%. Uncheck Transform objects.
This will create an action decreasing the stroke weight. Unfortunately, the path cannot contain a fill pattern or it will increase its size too.
Make another action with 110% do increase it.
See the image below: Plus a gif showing the action in action.
Bummer. I (at least) made a couple action key commands for making a doo-dad have a 1point stroke CTRL+ALT+SHIFT+F11, 2point stroke CTRL+ALT+SHIFT+F12
Which I'm hoping will take care of a lot of this, but not nearly as cool as +up -down.
Sometimes I think Adobe forgets about these little things when they are making a lot of money.
Such a shortcut does not exist. Scripting maybe, but probably more trouble than it's worth.
The easiest method that exists is to select the stroke, click in the stroke weight field in the control panel or the stroke panel and hit the arrow key up or down to increase and decrease he weight in small amounts and hit the those keys while holding down the option+shift (Mac) or alt+shift keys (PC) for greater increments.
