When at the text console the console driver traps ALT-Fx and switches virtual screens to the appropriate virtual terminal. When in X the X server traps CTRL-ALT-Fx and switches control to the appropriate virtual terminal. There exists a command-line command to do this as well, 'chvt' which is part of the kbd package. > For the specific task you mention, IIUC what you are asking, a <CTL>- > <ALT>-<RIGHT|LEFT> is an event that also causes the switch to another > screen. <CTL>-<ALT>-<TAB> rotates among desktop and panel focus, and > <SHIFT>-<TAB> rotates focus through apps in a virtual desktop.

These are handled by the window manager of choice, the X server only traps CTRL-ALT-Fx, CTRL-ALT-BKSPC, CTRL-ALT-KEYPAD-ADD, CTRL-ALT-KEYPAD-SUB, CTRL-ALT-KEYPAD-MUL, CTRL-ALT-KEYPAD-DIV. > Given all that, if it is valid, your task would be to write a > small app > for X that provides an "event" to which the existing > management software > would respond.

You can program a lot of powerful keyboard macros with KDE which aren't set by default, I'd say you can do so in Gnome or XFCE, but I don't know as I don't use those. -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.
