- {{{1}}}
Note that this is the same as {{P1}} but it puts a bullet in front of the parameter. This is useful for templates and modules that demand a "rowtemplate" for output, and not much else. Here's the documentation from {{P1}}:
The templates P1 and P2 simply return the first respectively second unnamed input parameter respectively. For example:
{{P1|foo|bar|baz}}returns foo{{P2|foo|bar|baz}}returns bar
These templates can be used inside other templates as an alternative to the {{#switch}} parser function, to switch between outputs based on whether the input is "1" or "2":
{{P{{{1}}}|output if 1|output if 2}}
Using {{#switch}}, this syntax is equivalent to
{{#switch:{{{1}}}|1=output if 1|2=output if 2}}
except that the parser function strips whitespace between parameters whereas the templates don't.
