+.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 XkbKeyNumActions
+computes the number of actions associated with the key corresponding to
+.I keycode.
+This should be the same value as the result of
+.I XkbKeyNumSyms.
+.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;
