Also,
Filters can be used as if tests. The nicest version is when testing the value
of a field.
For example if you had a field called display-code with the value yes or no,
you can do this for the current tiddler;
<$list filter="[is[current]display-code[yes]" variable=null>
Do or display what is here eg the code
By setting the variable the current tiddler remains the tiddler it is in so
{{!!fieldname}} works
</$list>
There if solutions out there, see evans plugins, personaly I find more value in
using filters.
The setwidget can compute filters as well and tge reveal widget can also make
comparisons.
