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.

Admin Menu Slide is a simple plugin that adds a feature to hide admin menu and make it slide when hovering on the edge of the screen. Works exactly like WordPress collapse menu – you can toggle the feature on/off by clicking a button, which is at the bottom of admin menu. When enabled, admin pages have full screen width.
