Quoted File Names
You can quote an absolute file name to prevent special
characters and syntax in it from having their special effects.
The way to do this is to add /: at the beginning.
For example, you can quote a local file name which appears remote, to
prevent it from being treated as a remote file name. Thus, if you have
a directory named /foo: and a file named bar in it, you
can refer to that file in Emacs as /:/foo:/bar.
/: can also prevent ~ from being treated as a special
character for a user's home directory. For example, /:/tmp/~hack
refers to a file whose name is ~hack in directory /tmp.
Likewise, quoting with /: is one way to enter in the minibuffer
a file name that contains $. However, the /: must be at
the beginning of the minibuffer in order to quote $.
You can also quote wildcard characters with /:, for visiting.
For example, /:/tmp/foo*bar visits the file /tmp/foo*bar.
However, in most cases you can simply type the wildcard characters for
themselves. For example, if the only file name in /tmp that
starts with foo and ends with bar is foo*bar, then
specifying /tmp/foo*bar will visit just /tmp/foo*bar.
Another way is to specify /tmp/foo[*]bar.
