Yes, it is possible. Here's how:
By default, the items in a TOC display use the *title* of each tiddler.
However, if you define a *caption* field for a tiddler, the TOC will use
that text instead. This is most often used to bypass the CamelCase name of
the tiddler (e..g, "Hello there", instead of "HelloThere") or to provide a
longer, more prosaic alternative (e.g, "Greetings and Felicitations!").
However, the caption text can also contain other wiki syntax, such as the
"@@" styling syntax, which lets you specify CSS classnames or inline
styles. For example, suppose you want a TOC item to be displayed using red
text. To do this, you could write the following in the caption field for
that tiddler:
@@color:red; Text goes here@@
Alternatively, for more "global" control over the appearance, you could use
a CSS classname (e.g., "myTOC"), like this:
1) First, define a stylesheet tiddler (tagged with $:/tags/Stylesheet),
containing
.myTOC { color:red; }
2) Then, in the caption field of the desired TOC item, write:
@@.myTOC Text goes here@@
The advantage of the classname method is that you then have centralized
control over the styling for *all* similar TOC items, without having to
separately re-edit the caption entries of each item. Thus, if you decide
to change the color, or add other CSS attributes, you only have to change
the stylesheet tiddler. For example:
.myTOC { color:green; font-size:150%; border:1px solid; }
