Undo: I wouldn't make this particular change, especially as part of this project. Having "Functions" be at the top of a column seems right; burying it under "Other" seems wrong. On the other hand, I don't know why "Type test functions" is before Functions; I'd move it over to after "Functions" or after "Mathematical". But again, Not This Project.

Recommendation: I would order these as
- name=value
- object
- [[name,value]]
- [[name]]
because I think name=value is the most likely variant.

Opinions solicited: There is an argument that this and has_key() belong over in the "Functions" section.

Discuss: Hmm. Using "string" there was deliberate, to emphasize that it was an arbitrary string expression, as opposed to an limited-to-identifier-and-constant name for the next.

Futures: I have mixed feelings about the "name" style, with the quotes. There are examples both ways through the cheat sheet, showing a sample value or showing the name of the argument. One would hope that people would understand that "name" is a sample and that you could use an arbitrary string expression there, but I've seen people who think that in cube([10,10,10]) the brackets are part of the syntax of cube(), or that in rands(1,10,1)[0] the [0] is part of the syntax.
It's certainly fine for now.
We should also work on consistency in how argument names are presented; we have cases where they are plain text, are part of the link or not, are gray, are italics. We have most functions not mentioning their arguments, but a couple do. But Not This Project.

Change: anchors for other functions are in lower case.
@jordanbrown0 could you take a look? I am also ok if you want to take this over since you already edited this cheat sheet.
