+.SH DESCRIPTION
+.LP
+Actions associated with the XkbRedirectKeyAction structure generate KeyPress and KeyRelease events
+containing a keycode different from the key that was pressed or released.
+
+The
+.I type
+field for the XkbRedirectKeyAction structure should always be XkbSA_RedirectKey.
+Key presses cause a KeyPress event for the key specified by the
+.I new_key
+field instead of the actual key. The state reported in this event reports the current effective
+modifiers changed as follows: any real modifiers selected by the
+.I mods_mask
+field are set to corresponding values from the
+.I mods
+field. Any real modifiers bound to the virtual modifiers specified by the
+.I vmods_mask0
+and
+.I vmods_mask1
+fields are either set or cleared, depending on the corresponding values in the
+.I vmods0
+and
+.I vmods1
+fields. If the real and virtual modifier definitions specify conflicting values for a single modifier,
+the real modifier definition has priority.
+
+Key releases cause a KeyRelease event for the key specified by the
+.I new_key
+field instead of the actual key. The state for this event consists of the effective keyboard modifiers
+at the time of the release, changed as described previously.
+
+The XkbSA_RedirectKey action normally redirects to another key on the same device as the key that
+caused the event, unless that device does not belong to the input extension KeyClass, in which case
+this action causes an event on the core keyboard device. (The input extension categorizes devices by
+breaking them into classes. Keyboards, and other input devices with keys, are classified as KeyClass
+devices by the input extension.)
+
+The
+.I vmods_mask0
+and
+.I vmods_mask1
+fields actually represent one
+.I vmods_mask
+value. Xkb provides macros to convert between the two formats.
+
+
+.I XkbSARedirectSetVModsMask
+sets the
+.I vmods0
+and
+.I vmods1
+of
+.I act
+from
+.I v.
