This plugin is ultra lightweight. It adds a media button above the tinyMCE editor on both the page and post editor, which when pressed copies a shortlink to your clipboard.
The idea behind this plugin is to add short-linking capabilities, without all the bloated code found in other plugins. This plugin does not alter the database, nor is any data saved or collected. It uses the built in WordPresspost/page ID’s in the URL.

Use shortlinks instead of permalinks in Jetpack sharing buttons
<ul>
<li>If you haven’t set up any shortlink plugin on your site, the sharing buttons will use the default numerical permalinks</li>
<li>If you have enabled WP.me Shortlinks in Jetpack, the sharing buttons will use them</li>
<li>If you’ve installed another plugin to create custom shortlinks, the sharing buttons will use them</li>
</ul>
Important: for this plugin to work, you must activate <a href="https://wordpress.org/extend/plugins/jetpack/" rel="ugc">Jetpack</a> first, and activate the Sharing module.
This plugin is a work in progress. You can report issues <a href="https://wordpress.org/support/plugin/jetpack-shortlinks-for-sharing-buttons/" rel="ugc">here</a>, or submit a pull request <a href="https://github.com/jeherve/jp-sd-custshortlink" rel="nofollow ugc">on GitHub</a>.
