tltt stands for "template link with tooltip". "tt" also can stand for the <tt> tag that surrounds it.

Like {{tl}} (see documentation), with an additional parameter for the tooltip. This will be displayed when user hovers over the curly braces. (Try it right here: {{Any template}}!)

The template is meant to be used in pages such as {{TestTemplates}}, where it is desirable to provide a bit more explanation for a template than what its name reveals.

Differently from {{tl}}, the font is set in monospace, so that all text appears in non-proportional font.

The template also permits up to two named parameters, like so:

{{tltt|Template name|Tooltip text|par=First parameter=1|par2=Second parameter=2}}

Produces:

{{Template name|First parameter=1|Second parameter=2}}
  • On some systems, the text only displays when user hovers over the curly braces, not over the link itself.
  • It is not possible to include double quotes in the text. Use single quotes instead.
  • {{tltt2}} - allows one sample parameter
  • {{tltt/tip}} - inform user that tooltips can be displayed
  • {{tltts}} - where subst: is required
