Name        : xkeyboard-config
Product     : Fedora 16
Version     : 2.3
Release     : 3.fc16
URL         : http://www.freedesktop.org/wiki/Software/XKeyboardConfig
Summary     : X Keyboard Extension configuration data
Description :
This package contains configuration data used by the X Keyboard Extension
(XKB), which allows selection of keyboard layouts when using a graphical
interface.

--------------------------------------------------------------------------------
Update Information:

The previous version of xkeyboard-config included the key combinations to clear
and/or kill grabs in the default keymap. This enabled users to get around screen
locks that use grabs to prevent input to other applications (e.g.
gnome-screensaver). This update moves the definition of the key combinations to
a XKB option that must be explicitly enabled by the user.
