Is there a hotkey to switch between tabs in Ubuntu's native terminal app? I'm using the netbook version of ubuntu.
To switch between tabs you can use Alt-n, where n is the tab ordinal number.
By the way, this works the same in Gedit.
I'm guessing you mean the default distributed (pre-installed) gnome-terminal.
You can set your own shortcuts easily, just go to menu
Bonus tip: If you wanna take a look to the real "native terminal" or tty (teletype interfase) just hit Ctrl+Alt+F1 (It works with almost any Function key), and don't panic, you can come back to the "graphical interfase" by hitting Ctrl+Alt+F7
