How can I switch between windows of the same application?

I often have more than ten windows open at the same time and some of them are of the same applications, notably gnome-terminal.

Often when I am currently on one terminal, I just want to get to another terminal. With Alt-Tab you have to choose from windows of all the applications, which is a pain. Even with Gnome3 which groups windows by applications and gives preview of windows with Alt-` it isn't enough because it's hard to distinguish terminal windows from previews. You can only tell which terminal does what when the full view is shown in most cases.

So is there an application/windowing system/gnome shortcut that shows you only other windows of the same application when you are switching?

This is old question, but I had the same problem and found Alt + ` switches the windows of the same application. Thus, sharing the same for reference.

If you install the CompizConfig Settings Manager then you can access and change the Compiz settings that can do this. Once installed launch it via System->Preferences.

If you normally use Alt+Tab then go the "Static Application Switcher". (This plugin shows quite small previews.)

If you normally use Windows/Super+Tab then go to "Shift Switcher Plugin". (This plugin shows quite large previews.)

In the settings for either of the plugins you can set the keyboard (or mouse) shortcut for Next Window (Group) and/or Previous Window (Group).

(Note: as well as the Static Application Switcher and Shift Switcher you may wish to experiment with the Application Switcher and Ring Switcher)
