+.SH DESCRIPTION
+.LP
+A key action defines the effect key presses and releases have on the internal
+state of the server. For
+example, the expected key action associated with pressing the Shift key is to
+set the Shift modifier.
+There is zero or one key action associated with each keysym bound to each key.
+
+Just as the entire list of key symbols for the keyboard mapping is held in the
+.I syms
+field of the client map, the entire list of key actions for the keyboard mapping
+is held in the
+.I acts
+array of the server map. The total size of
+.I acts
+is specified by
+.I size_acts,
+and the number of entries is specified by
+.I num_acts.
+
+The
+.I key_acts
+array, indexed by keycode, describes the actions associated with a key. The
+.I key_acts
+array has
+.I min_key_code
+unused entries at the start to allow direct indexing using a keycode. If a
+.I key_acts
+entry is zero, it means the key does not have any actions associated with it. If
+an entry is not zero,
+the entry represents an index into the
+.I acts
+field of the server map, much as the
+.I offset
+field of a KeySymMapRec structure is an index into the
+.I syms
+field of the client map.
+
+The reason the
+.I acts
+field is a linear list of XkbActions is to reduce the memory consumption
+associated with a keymap.
+Because Xkb allows individual keys to have multiple shift levels and a different
+number of groups per
+key, a single two-dimensional array of KeySyms would potentially be very large
+and sparse. Instead, Xkb
+provides a small two-dimensional array of XkbActions for each key. To store all
+of these individual
+arrays, Xkb concatenates each array together in the
+.I acts
+field of the server map.
+
+The key action structures consist only of fields of type char or unsigned char.
+This is done to
+optimize data transfer when the server sends bytes over the wire. If the fields
+are anything but bytes,
+the server has to sift through all of the actions and swap any nonbyte fields.
+Because they consist of
+nothing but bytes, it can just copy them out.
+
+.I XkbKeyAction
+returns the key action indexed by
+.I idx
+in the two-dimensional array of key actions associated with the key
+corresponding to
+.I keycode.idx
+may be computed from the group and shift level of interest as follows:
+.nf
+
+ idx = group_index * key_width + shift_level
+.fi
+.SH STRUCTURES
+.LP
+The KeySymMapRec structure is defined as follows:
+.nf
+
+ #define XkbNumKbdGroups 4
+ #define XkbMaxKbdGroup (XkbNumKbdGroups-1)
+
+ typedef struct { /\(** map to keysyms for a single keycode
+*/
+ unsigned char kt_index[XkbNumKbdGroups]; /\(** key type index for
+each group */
+ unsigned char group_info; /\(** # of groups and out of range group
+handling */
+ unsigned char width; /\(** max # of shift levels for key */
+ unsigned short offset; /\(** index to keysym table in syms array
+*/
+} XkbSymMapRec, *XkbSymMapPtr;
