These are useful for email events, and possibly some custom messages.

Every item in the user's user.xml file can be referenced with a "%user_<tag-name>%". This is the first area it attempts to match with variables that start with "%user_".

{all}  (a raw dump of the item's info.)
{the_file_path}
{the_file_name}
{the_file_size}
{the_file_size_formatted}
{the_file_error}
{the_file_start}
{the_file_end}
{url}
{display}
{user_time}
{the_file_path1}  (piece #1 of the file's path)
{the_file_path2}  (piece #2)
{the_file_path3}  (piece #3, etc.)
{the_file_path4}
{the_file_path5}

Next it searches the user properties in memory about the current session:
