Yakuake

is a terminal emulator that will slide down your screen when you press a shortcut key. It allows very fast access to your shell from any program.

It is similar to other programs like Guake and Tilda.

Change Shortcut
The default shortcut to open  is. This conflicts with the default shortcut to open developer tools in browsers. I personally use  as the key is easy to reach and its default functionality is useless to me.

To change this, open application, open section  , and choose. In that screen, select  as component and click on the shortcut to change it.
