Hi MJL,

mario addressed the basics of macro invocation in his reply, so I'm
just going to respond to the specific question you asked - how to 'pre-
populate' tiddler content when creating a new tiddler (which, btw, has
been answered *many* times over the years...)
The <<newTiddler>> macro has optional parameters tht allow you to
define initial values for the title, tags, text and custom fields of a
tiddler. For your purposes, the parameter you want is "text:..."
<<newTiddler text:"this is the default text for the new tiddler">>
Unfortunately, the macro syntax is a bit restrictive when specifying
text: it must be enclosed in either single- or double-quotes (which
means you can't use BOTH within the text), and cannot contain TW
macros (the closing ">>" within the text would break the surrounding
macro definition!). Also, if the default text is lengthy (or multi-
line), it can become ridiculously difficult to read and understand the
nesting of syntax within the surrounding macro.
Fortunately, there is simple method of specifying the text that avoids
the ugliness: first store the desired default text in a separate
tiddler (e.g., [[SomeTiddler]]) and then retrieve that tiddler content
for use as the value of a macro param, by using the *evaluated
parameter* syntax to invoke the TWCore's store.getTiddlerText()
function, like this:
<<newTiddler text:{{store.getTiddlerText("SomeTiddler")}}>>
The result is that the contents of SomeTiddler are pre-loaded into the
text field of the new tiddler when it is initialized for editing.
QED.
enjoy,
