-.SH DESCRIPTION
-.LP
-The
-.I group_info
-field of an XkbSymMapRec is an encoded value containing the number of groups of
-symbols bound to the
-key as well as the specification of the treatment of out-of-range groups. It is
-legal for a key to
-have zero groups, in which case it also has zero symbols and all events from
-that key yield NoSymbol.
-To obtain the number of groups of symbols bound to the key, use
-.I XkbKeyNumGroups.
-To change the number of groups bound to a key, use
-.I XkbChangeTypesOfKey.
-To obtain a mask that determines the treatment of out-of-range groups, use
-.I XkbKeyGroupInfo
-and
-.I XkbOutOfRangeGroupInfo.
-
-The keyboard controls contain a
-.I groups_wrap
-field specifying the handling of illegal groups on a global basis. That is, when
-the user performs an
-action causing the effective group to go out of the legal range, the
-.I groups_wrap
-field specifies how to normalize the effective keyboard group to a group that is
-legal for the
-keyboard as a whole, but there is no guarantee that the normalized group will be
-within the range of
-legal groups for any individual key. The per-key
-.I group_info
-field specifies how a key treats a legal effective group if the key does not
-have a type specified for
-the group of concern. For example, the Enter key usually has just one group
-defined. If the user
-performs an action causing the global keyboard group to change to Group2, the
-.I group_info
-field for the Enter key describes how to handle this situation.
-
-Out-of-range groups for individual keys are mapped to a legal group using the
-same options as are used
-for the overall keyboard group. The particular type of mapping used is
-controlled by the bits set in
-the
-.I group_info
-flag, as shown in Table 1.

-.\"--- Chapter 10
-The Xkb extension is composed of two parts: a server extension, and a
-client-side X library extension.
-This chapter discusses functions used to modify controls effecting the behavior
-of the server portion
-of the Xkb extension. X Library Controls discusses functions used to modify
-controls that affect only
-the behavior of the client portion of the extension; those controls are known as
-Library Controls.
-
-Xkb contains control features that affect the entire keyboard, known as global
-keyboard controls. Some
-of the controls may be selectively enabled and disabled; these controls are
-known as the
-.I Boolean Controls.
-Boolean Controls can be turned on or off under program control and can also be
-automatically set to an
-on or off condition when a client program exits. The remaining controls, known
-as the
-.I Non-Boolean Controls,
-are always active. The XkbControlsRec structure describes the current state of
-most of the global
-controls and the attributes effecting the behavior of each of these Xkb
-features. This chapter
-describes the Xkb controls and how to manipulate them.
-
-There are two possible components for each of the Boolean Controls: attributes
-describing how the
-control should work, and a state describing whether the behavior as a whole is
-enabled or disabled.
-The attributes and state for most of these controls are held in the
-XkbControlsRec structure.
-
-You can manipulate the Xkb controls individually, via convenience functions, or
-as a whole. To treat
-them as a group, modify an XkbControlsRec structure to describe all of the
-changes to be made, and
-then pass that structure and appropriate flags to an Xkb library function, or
-use a
-XkbControlsChangesRec to reduce network traffic. When using a convenience
-function to manipulate one
-control individually, you do not use an XkbControlsRec structure directly.
-
-The Xkb controls are grouped as shown in Table 2.
