What is auto-select?
Searching the documentation I find references to various commands that turn on "auto-select mode"; however, there are no matches for "auto-select" other than those commands, and no matches for "auto select" (without the hyphen) at all. I'm sure I once knew what this was, but I don't now. What is it? Please check that the answer to this is in the documentation even though I am not finding it, and if it is, tell me where.
