I just installed 11.04 and am using the dvorak keyboard layout.
When I press Ctrl+Alt+T to bring up the terminal it doesn't bring it up, but when I press Ctrl+Alt+Y (the key that would be t in qwerty) it brings up a terminal.
I have no other keyboard layouts installed, but have switched caps lock and control.
In the Keyboard Shortcuts configuration it shows up as Ctrl+Alt+T to launch a terminal.
I would like the terminal shortcut to respect the keyboard layout.
