The extension adds several entries to the context menu, that allows you to send Text or URLs that contain GPS-coordinates directly to the OSM Links website. It basicially replaces copying the text/url, opening the OSM Links website and filling out the form.
Additional context-menu entries will appear, when you..
* right-click on a link
* right-click on selected text
* right-click anywhere on the page, if the current page contains a link with the link-text "Permalink"
It is configurable whether the website should be opened in the current tab or a new one (and if the new one should be focused immediately).
OSM Links is a collection of useful OpenStreetMap links (mostly maps which will be automatically extended with the given coordinates). For more information about OSM Links, visit the Homepage.
