[% somevariable | html %]

is a shorthand for

[% somevariable FILTER html %]

Another handy manpage is on virtual methods, the equivalent of Perl
operators like map, grep, sort on arrays and hashes
http://template-toolkit.org/docs/manual/VMethods.html

particularly the custom ones
http://template-toolkit.org/docs/manual/VMethods.html#section_Defining_Cust=
om_Virtual_Methods
which let you add new operators, e.g. for formatting currency
