Shortcut {{\sandbox}}

{{ When in sandbox ( | return this, otherwise) return "/sandbox" ( | else return this) }}

Returns "/sandbox" – or, if supplied, the first unnamed parameter ("return this" above) – if the template detects that the page where it is transcluded is a subpage named "sandbox" (i.e. a sandbox page); otherwise it returns nothing – or, if supplied, the second unnamed parameter ("else return this" above). It corresponds to {{When pagename is |/sandbox={{{return this|/sandbox}}} |other={{{else return this|}}}}}.

This can be useful to e.g. switch the version of a template used in its /doc[umentation] to the version in its sandbox (by replacing 𐍆𐌰𐌿𐍂𐌰𐌼𐌴𐌻𐌴𐌹𐌽𐍃:Mono ... on the /doc page with 𐍆𐌰𐌿𐍂𐌰𐌼𐌴𐌻𐌴𐌹𐌽𐍃:Mono ...) when that documentation is transcluded on the template's sandbox page.
