Template:Navpop
This template is used to simplify manual installation of Wikipedia:Tools/Navigation popups.
Usage
Add {{subst:navpop}} to Special:MyPage/common.js. This will add the following code:
// Wikipedia:Tools/Navigation popups
mw.loader.load('/w/load.php?modules=ext.gadget.Navigation_popups');
Alternatively, {{subst:navpop}} can be added to a specific skin (rather than a file that works for all skins, as above):
Note: Special:MyPage/skin.js will redirect to the file for your current skin, if JavaScript is enabled.
