After last week’s post on background masks for dimension objects, I poked around through my archives and realized I’ve never posted on regular text masks. I know I put it in a demo video, but I guess it never got its own post. Let’s fix that.
When you’re creating or editing multiline text, there’s a button the Formatting panel called Background Mask.
Click on it, and you’ll get a dialog box where you can set the offset factor and the fill color.
The offset factor, how far the mask extends beyond the text, is relative to the text height. A factor of 1 keeps the mask the same size as the text. A factor of 1.5 provides a border equal to half the text height all the way around. The maximum factor for the mask is 5.0.
For the fill color, you can either pick a standard color, or use the background color of the drawing, which basically means it’ll plot clear.
New in 2012, the values you choose when creating a mask for a *new* text object will be remembered for the next time you want to apply a mask. (Previously, they defaulted to 1.5 and red every time.)
The reason this only works for new text objects is that background masks are a property of the text. See?
So you have to actively set the variables for a new object before they’ll persist.

The ability to define background masks in text style settings sure would come in handy, wouldn't it?

Great tip Kate.
I particularly like the use of the properties palette. It's may favourite tool!
I put together a post on all the groovy things that you can do with the properties palette that your readers might enjoy:
