B<< double quotes >> are paired and can contain any character inside,
with some care. If you need to put double quotes inside, you have to
escape with a backslash. Also, if you want to insert a literal
backslash, you have to prepend it with another backslash. In general,
every time you put a backslash, the following character is taken as-is
and the escaping backslash is tossed away. So the following:

"\'\a\ \v\e\r\y\ \s\t\r\a\n\g\e\ \k\e\y\'"

is interpreted as:

'a very strange key'

(including the single quotes). No, there is no specific handling for
other characters that are normally escaped, i.e. C<\n> means C<n>, not a
newline (C<crumble> has no problem dealing with a literal newline
though).
