Tilda is just another Linux terminal emulator, but it has some useful properties coming with it, like, no borders, transparency, but most important, it can appear on your window with the press of a key.
As usually it is very easy, just ask your package manager to install if for you.
sudo aptitude install tilda
sudo emerge tilda
I have it running on both, and with Gentoo using Fluxbox, but with +gtk flag in my
make.conf maybe it is not necessary.
Once installed the first time you run it, you will get the properties dialog box, there you can manage the position of the window, the transparency level, the character size and a lot of other features, the last tab there is for keybindings and you can select the key that will make the Tilda window appear on your screen, by default is F1 but that key is also used to get help in a lot of other applications, you may want to change it, I change it to Windows-key+F1
This is how it looks like:
As you can see it appears on the screen in the position you have defined in properties, each time you press the “fire” key, and once you have finished with it, just press the key again and it will disappear until the next time you call it, it will reside on memory, if you want to finish it, just enter
on the tilda screen and it will be completely closed.
To access the properties menu, just right-click on it and select properties.
