Terminator Toggle Opacity Keyboard Shortcut
Do you know any keyboard shortcut to adjust or toggle the terminal's opacity without right clicking and going into preferences? That would be so sweet if that is possible.
Terminator does not support hotkeys to change background opacity or color:
To my mind, rewriting the config file on the fly is the wrong way to achieve the things you want. A much better way would be the dbus server that we've started to introduce. It is designed to allow things running inside a terminal to communicate with Terminator and send commands that will affect the terminal. For now it only exposes commands for splitting, but over time I hope we will be able to extend this to include things like colours and transparencies, etc.

CompizConfig allows you to change any window's opacity with a keyboard shortcut. The effect is different than Terminator background opacity, but it's good enough for me -- I want to glimpse the web page behind my terminal.
sudo apt-get install compizconfig-settings-manager
