The Pre button toggles the preformatted style on the selected text or the current line (applies <code><pre></code> tag to blocks). 
The Code button toggles the code style on the selected text or the current word (applies <code><code></code> tag to inline elements).
The default shortcuts for the buttons are:
<ul>
<li>Ctrl+Q – Pre</li>
<li>Ctrl+D – Code</li>
</ul>
In the admin Settings submenu it’s possible to change these shortcuts. 
Press a key combination in the text fields with the Ctrl key included and the text will be filled automatically. Or you can type it manually.
Some combinations may conflict with the default editor or browser shortcuts. 
So check them on your instance.
You may use these types of shortcuts:
<ul>
<li><code>Ctrl+B, .., Z (except AXCV)</code></li>
<li><code>Ctrl+0, .., 9</code></li>
<li><code>Ctrl+[symbols] (-=`[];'\/,.)</code></li>
<li><code>Ctrl+F1, .., F12</code></li>
<li><code>Ctrl+Pad0, .., Pad9</code></li>
<li><code>Ctrl+Pad/, Pad*, Pad+, Pad.</code></li>
<li><code>Ctrl+Shift+...</code></li>
<li><code>Ctrl+Alt+...</code></li>
<li><code>Ctrl+Shift+Alt+...</code></li>
</ul>

Ever want your own shortcuts without mucking about with permalink structures? The Link Shortcut plugin allows you to create short (random numbers and letters, or short words) URLs under your blog’s domain that redirect (301 or 302, your choice) a user to other pages, either in your site or on another site.
In other words, instead of sending this url to the author’s plugin page: 
http://www.husani.com/ventures/wordpress-plugins/linkshortcut/
This shortcut could be created simply by installing this plugin and adding a link, via the same traditional WordPress UI we all know and love: 
http://www.husani.com/link123
You can also specify a specific “subdirectory” to be present in all Link Shortcut URLs: yourblog/go/STRING, for example.
YOU MUST USE NON-UGLY PERMALINKS FOR THIS PLUGIN TO WORK. Your permalink structure cannot be yourblog.com?p=84, it must be date-based, name-based, etc.
IMPORTANT: Link Shortcut creates a table inside your database. Upon deactivation, the plugin creates a backup table and copies records to it before removing the main table. If you decide to activate the plugin again — or have installed an upgrade — it automatically copies your backed up links to the newly created table. You can also delete the backup table if you remove Link Shortcut permanently.
