Tilda is a Linux terminal taking after the likeness of many classic terminals
from first person shooter games, Quake, Doom and Half-Life to name a few,
where the terminal has no border and is hidden from the desktop till a key or
keys is hit.
*NOTE* : Could any KDE-user package yakuake? is another package similar to tilda,
but for KDE. Is _really_ nice to use the shell like a quake
