Template:\sandbox
 | This page is not a sandbox. It should not be used for test editing. To experiment, please use the Wikipedia sandbox, your user sandbox, or the other sandboxes. |
Usage
Returns "/sandbox" 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.
This can be useful to e.g. switch the version of a template used in its documentation to the version in its sandbox (by replacing {{template name}} on the /doc page with {{template name{{\sandbox}}}}) when that documentation is transcluded on the template's sandbox page.
