With Smart Admin Search you can quickly find contents in the WordPress dashboard without going up and down on the admin menu.
Just click on the top-right link or press a keyboard shortcut to open the search box, then type what you are looking for. Easy!
Currently Smart Admin Search can find:
<ul>
<li>admin menu items</li>
<li>posts</li>
<li>pages</li>
<li>users</li>
<li>media</li>
<li>custom post types contents</li>
</ul>
Configuration
Settings for the plugin are available on the Settings -> Smart Admin Search page.
Some things you can do in the settings page:
<ul>
<li>configure the keyboard shortcut to open the search box.</li>
<li>disable search functions you don’t need.</li>
<li>change layout of the search link on the admin bar</li>
</ul>
Permissions
The search box can be used by users of any role. Each user will get results available for the assigned role.
For pages and posts results, these actions will be triggered on result selection, according to the user permissions:
<ul>
<li>edit item</li>
<li>view item</li>
<li>show a message if no access to the item is allowed</li>
</ul>

In modern operating systems you can press a Start or Spotlight key, type a few letters of the operation you need, and choose it. There’s no need to waste time clicking around in the menus looking for your command. This plugin gives you the same capability for WordPress’s dashboard and its features.
The plugin places a search box at the top of the menu at the top left of WordPress’s dashboard. (That menu is at the top right if you use a right-to-left language such as Rohingya or Arabic.) Click in that menu and type a few letters. You’ll see a drop-down list of matching commands. Use arrow keys to select the command you want, and press Enter or Tab.
You can press Shift twice rapidly instead of clicking in the search box. So, for example, to go to your orders in your WooCommerce store, type this.
Shift Shift o r d e r s Enter
Tnat’s it.
How does this plugin work? It is lightweight. It sends its small JavaScript file to your browser for every dashboard page. That JavaScript analyzes the WordPress menus and prepares the dropdown list.
