How to make "CTRL + ALT + T" open new Terminal window when one is already open?

The funny thing is that on Unity, CTRL + ALT + T does open a new window, apparantly not on Gnome...

To make the setup:

1. First disable the existing command/key combination with the command:

   gsettings set org.gnome.settings-daemon.plugins.media-keys terminal ""
   

   Which will make CTRL + ALT + T "available" again for another command.

2. Now open keyboard settings: System Settings > "Keyboard" > "Shortcuts" > "Custom Shortcuts". Click the "+" and add the command:

   gnome-terminal --window-with-profile=<profilename>
   

   to CTRL + ALT + T, where <profilename> is the name of your profile, most likely Default

From man gnome-terminal:

   --window-with-profile=PROFILENAME
             Open  a new window containing a tab with the given profile.
             More than one of these options can be provided.

It's pretty easy to make Ctrl+Alt+T alive in gnome:

1. Search for Keyboard shortcuts in Gnome home menu

2. Add a custom shortcut in Keyboard

3. Add (+)

   • Name: gnome-terminal
   • Command: gnome-terminal
   • Ctrl+Alt+T
