{{tiddler.title}} is an "evaluated parameter"... Think of {{ and }} as
special kinds of 'quotes'. However, rather than simply using the
parameter value as literal text, the enclosing {{...}} syntax tells
TW's macro handler to invoke the contents as javascript code in order
to compute a text value that will be then be passed along as the
parameter. In this particular use-case, the code is simply a
reference to a property (title) of a global object (tiddler) that is
automatically set by the TW core.
Note: If you are using TW242 or earlier, the global 'tiddler' variable
was not being set to a useful value. You need to be using TW243 or
above, or install
http://www.TiddlyTools.com/#CoreTweaksArchive
which contains 'obsolete' tweaks that are no longer needed for the
current version (TW250+).
