gnome-terminal-2.24.1-1.fc10.i386 Using alt+1 does not jump to the first tab. I can still use cntl+pgup to change tabs but none of the jump to tab shortcuts work. Downgrading to gnome-terminal-2.24.0-2.fc10.i386.rpm fixes the issue and I can use alt+1 to jump to tab #1. I'd also like to complain that the ability to change the shortcut key for jump_to_tab disappeared between the F9 and F10, but that isn't exactly the same bug... I cannot live with a gnome-terminal that doesn't include a jump to tab shortcut key.
Fixed in 2.24.1-2.fc10
