bug#12695: 24.2.50; Describe file-name cache at (emacs) `File Conveniences'

[Drew Adams]

This is a node about "convenient facilities for finding" files.  It
should mention the file-name cache and cross-reference node `File Name
Cache'.  That feature too provides a way to quickly find files that
might be far from the current directory.
