Bug 357965

[Regression] Konsole does not allow its hotkey to show/hide Konsole (à la Yakuake, Kuake, Guake, Tilda, the "terminal emulator" present in Quake and other games, etc.). That functionality is known as the "background mode" of Konsole.

Previously, a real Konsole survey was done. It was answered by more than 8000 people and the background mode was developed because of this. Robert Knight, a former main developer of Konsole, wrote in http://kdemonkey.blogspot.com.es/2007/04/easter-holiday-terminal-update.html: 

> Implemented a Yakuake-style 'background mode' for Konsole. This means that a shell session
