"global" include (or not)

I have leafed through the manual (yep, I printed it out) looking for a “global” method of turning on/off the “include in compile” setting so that I do not have to do it individually for folders/text.
I was hoping there might be a way to highlight several folders and/or texts and include/exclude them in the General Meta-data setting, but it doesn’t seem to work that way. Any advice appreciated!

Found it! Under “Contents” in the Compile panel, use Alt-click to select/deselect globally. Very useful.
