Ctrl - Tab key binding doesn't work in Linux

I have set a key binding in Emacs using:

(global-set-key (kbd "<C-tab>") 'switch-view )

: It 开发者_运维百科works in Windows but Emacs in Linux seems to ignore it. Any ideas why?

My version of Emacs is 23.2 running in text mode (.nw)

In text mode, Emacs depend upon the terminal or the console for keys combination. Terminals and consoles don't support as many keys combination as Xorg and windows do, and C-TAB is a combination that don't exist in text mode: TAB is already the same than C-i, and C-C-something don't exists.

The window manager you are using is most likely 'kidnapping' it.

On mine (which is KDE), C-tab cycles through applications on the current desktop. You can configure which keystrokes should be ignored though... but your best bet may be to map switch-view to another key sequence in your ~/.emacs file.
