This node mentions about keys following `C-c', but only `{', `}', `<',
`>', `:', `;', control chars, digits, letters, and "other punctuation".
What about keys `-', `+', `@', `#', `%', `^', `&', `*', `=', etc.? These
are not mentioned.
I think, based on the mention of "other punctuation" coming just after
mention of the explicit list `{', `}', `<', `>', `:', `;', that all such
chars are intended by "other punctuation". I guess this because `<' and
`>', at least are not typically punctuation.
Could this doc please corrected to cover the cases of characters not
mentioned that are not really punctuation? I'd propose that they should
be explicitly covered by what is said for "other punctuation": they
should be reserved for minor modes.
But regardless of what the decision is, even if it is to not put any
restriction on the use of the unmentioned chars, can we please make the
convention explicit in their regard, so there is no question, e.g.,
whether a sequence such as `C-c -' is reserved for minor modes?
While there, could we also document the conventions for all other possible key combinations? What about e.g. keys involving the Meta, Super, Hyper, Alt, and Shift modifiers? What about C-F1 etc?
