Guake and Yakuake are drop-down terminal shells
Guake, or (if it’s a K Desktop Environment) Yakuake are “drop-down terminal shells” that appear when you press a button (usually F12).
If you usually open a terminal with every log in to your Linux desktop, there’s a more convenient (not to mention laaazy) way. Simply tell the OS to run Guake after your user’s successful login. In Openbox, you’d add it to your autostart.sh file
The Guake terminal will notify you that it has started, and then auto-hides itself until you “un-hide it” by pressing the F12 key. When you’re done with your current command-line stuff, simply press F12 again and Guake gets out of your way.
