+				This hook is called when MCServer receives a left-click packet from the {{cClientHandle|client}}. It
+				is called before any processing whatsoever is performed on the packet, meaning that hacked /
+				malicious clients may be trigerring this event very often and with unchecked parameters. Therefore
+				plugin authors are advised to use extreme caution with this callback.</p>
+				<p>
+				Plugins may refuse the default processing for the packet, causing MCServer to behave as if the
+				packet has never arrived. This may, however, create inconsistencies in the client - the client may
+				think that they broke a block, while the server didn't process the breaking, etc. For this reason,
+				if a plugin refuses the processing, MCServer sends the block specified in the packet back to the
+				client (as if placed anew), if the status code specified a block-break action. For other actions,
+				plugins must rectify the situation on their own.</p>
+				<p>
+				The client sends the left-click packet for several other occasions, such as dropping the held item
+				(Q keypress) or shooting an arrow. This is reflected in the Status code. Consult the
+				<a href="http://wiki.vg/Protocol#0x0E">protocol documentation</a> for details on the actions.
