comment Semitransparent outside “clipped” region?
Thanks for your help! One quick question: When I remove the preaction=clip, there is no change to the results (as far as I can tell). Why is that option there? Also (ok, two questions, I guess), based on the answer that you linked to, I would have expected preaction={clip, insert path=...}, but that doesn't have the correct result. So, could you explain why moving the insert path=... outside the preaction is the right thing to do? Sorry to ask so many questions; I just want to understand so I can better solve future problems that I run into.

This is a good idea too, but I'd rather not have to explicitly recreate the parts inside the red circle. I am greedy that way. :)

comment Semitransparent outside “clipped” region?
I like this answer for its simplicity without manually repeating the nodes a, b, and c, etc. One question: if I comment out the red circle (and use a different fill color for the rectangle-circle path, say, gray, just to see what is going on), I get a strange result in which only some of the area surrounding the circle is filled transparent gray. Using even odd rule doesn't seem to help. Do you know why?

I would've never thought of this idea! I agree that it's not quite ideal, but it seems to work great for my purpose. I'll wait to accept this answer, in case someone comes up with something else, but otherwise I'll try to remember to accept your answer in a day or so. Thanks so much for your help!

comment Parameters for newly-defined shapes
Stumbled upon this answer and would like to adapt it for some cargo cult programming. What do \tikz@mode and \tikz@options do here? They aren't listed in the manual.

comment How can I decide whether a key has had .value forbidden applied?
@JosephWright Is something like this what you meant? /handlers/.value forbidden/.prefix code = {\pgfkeyssetvalue{\pgfkeyscurrentpath/.@forb}{}} and then testing whether \pgfkeyscurrentpath/.@forb is defined. It seems to work great! Thanks for the idea. If you want to convert this to an answer, I would be happy to accept it.

@AndrewStacey If you and Joseph want to convert your comments to answers, I would be happy to accept one of them.

comment How can I decide whether a key has had .value forbidden applied?
@JosephWright That's good to know about l3keys. I guess that in this instance I'm forced to use pgfkeys. Your suggestion of modifying /handlers/.value forbidden/.code is a good one, and I'll have to decide whether it is worth going that route, or whether @AndrewStacey's solution is "good enough".

comment How can I decide whether a key has had .value forbidden applied?
@AndrewStacey I thought of that, too, but for some keys you might want to pass an empty argument which would then be forced to \pgfkeysnovalue by mistake. Given what you say, however, I guess it seems to be the best that one can do.

comment How to create a Beamer overlay \cover command, dual to \uncover?
Thanks, this does seem to do what I want! Could you explain a little bit why my first attempt failed and how your fix works? I'd like to understand more so that I can better solve these problems on my own. Comparing your definition of \beamer@startmycovered with \beamer@startcovered from beamerbaseoverlay.sty, it looks like you removed a \beamer@actions and a \beamer@smuggle from around the entire definition. What do these do? Thanks again!

@GonzaloMedina I just cropped it manually in GIMP (select, then crop to selection) and built the gif from that. I'm not sure what would be the easiest way to automate that.
