Binary package “yakuake” in ubuntu focal

Quake-style terminal emulator based on KDE Konsole technology

 YaKuake is inspired from the terminal in the Quake game: when you press a key
 (by default F12, but that can be changed) a terminal window slides down from
 the top of the screen. Press the key again, and the terminal slides back.
 It is faster than a keyboard shortcut because it is already loaded into memory
 and as such is very useful to anyone who frequently finds themselves switching
 in and out of terminal sessions.
