-        Types of keyboard interaction possible for layer shell surfaces. The
-        rationale for this is twofold: (1) some applications are not interested
-        in keyboard events and not allowing them to be focused can improve the
-        desktop experience; (2) some applications will want to take exclusive
-        keyboard focus.

-        <description summary="no keyboard focus is possible">
-          This value indicates that this surface is not interested in keyboard
-          events and the compositor should never assign it the keyboard focus.
-
-          This is the default value, set for newly created layer shell surfaces.
-
-          This is useful for e.g. desktop widgets that display information or
-          only have interaction with non-keyboard input devices.

-        <description summary="request exclusive keyboard focus">
-          Request exclusive keyboard focus if this surface is above the shell surface layer.
-
-          For the top and overlay layers, the seat will always give
-          exclusive keyboard focus to the top-most layer which has keyboard
-          interactivity set to exclusive. If this layer contains multiple
-          surfaces with keyboard interactivity set to exclusive, the compositor
-          determines the one receiving keyboard events in an implementation-
-          defined manner. In this case, no guarantee is made when this surface
-          will receive keyboard focus (if ever).
-
-          For the bottom and background layers, the compositor is allowed to use
-          normal focus semantics.
-
-          This setting is mainly intended for applications that need to ensure
-          they receive all keyboard events, such as a lock screen or a password
-          prompt.

-        <description summary="request regular keyboard focus semantics">
-          This requests the compositor to allow this surface to be focused and
-          unfocused by the user in an implementation-defined manner. The user
-          should be able to unfocus this surface even regardless of the layer
-          it is on.
-
-          Typically, the compositor will want to use its normal mechanism to
-          manage keyboard focus between layer shell surfaces with this setting
-          and regular toplevels on the desktop layer (e.g. click to focus).
-          Nevertheless, it is possible for a compositor to require a special
-          interaction to focus or unfocus layer shell surfaces (e.g. requiring
-          a click even if focus follows the mouse normally, or providing a
-          keybinding to switch focus between layers).
-
-          This setting is mainly intended for desktop shell components (e.g.
-          panels) that allow keyboard interaction. Using this option can allow
-          implementing a desktop shell that can be fully usable without the
-          mouse.

-        layer shell surfaces do not receive keyboard events; this request can
-        be used to change this.
-

+        Set to 1 to request that the seat send keyboard events to this layer
+        surface. For layers below the shell surface layer, the seat will use
+        normal focus semantics. For layers above the shell surface layers, the
+        seat will always give exclusive keyboard focus to the top-most layer
+        which has keyboard interactivity set to true.
 
         Layer surfaces receive pointer, touch, and tablet events normally. If
         you do not want to receive them, set the input region on your surface
         to an empty region.
