Gnome Terminal Modification

You will probably want to make modifications to your terminal window at some time. The Gnome terminal is a common terminal used by a lot of people but often people do not recognize all of the features that are available. This tutorial will help you with that configuration.

 

Here is a picture of the Gnome Terminal. If you choose Edit /Profiles you can create a new profile that will have different color backgrounds and text for easier viewing.

Right Click the colored bar and you will get the shortcuts to perform these tasks:

 

Minimize Alt+F9
Maximize Alt+F10
Move Alt+F7
Resize Alt+F8

You also have the option to always make the terminal visible on all workspaces. This is handy if you do a lot of work from the terminal. Or you can make it visible on only one workspace if you want.
