I’ve become quite fond of tabs thanks to Opera and Galeon, but just recently discovered (by accident) that gnome-terminal has tabs too.

Ctrl-Shift-T opens a new tab and Ctrl-PgUp and Ctrl-PgDown allow you to navigate up or down through them. They are especially convenient when you want to run a quick shell command, then go back to what you were doing.

Thank goodness for accidental keystrokes. I’ve learned a lot of cool features from them.
