+# Input Hotkey API
+
+Allows keyboard shortcuts (hotkeys) to be bound to an element's click event.
+
+# Example
+
+    <button
+        class="btn btn-default"
+        data-hotkey="b"
+        onclick="alert('B is for Banana!')">
+        Press "B" on your keyboard
+    </button>
+
+    <button
+        class="btn btn-default"
+        data-hotkey="shift+r"
+        onclick="confirm('Shift gears...?')">
+        Press "Shift + R" on your keyboard
+    </button>
+
+## Javascript API
+
+If you use a selector other than a button or a link, you will need to add the `hotkeyVisible` property to the hotkey config.
+
+    $('html').hotKey({
+        hotkey: 'ctrl+s, cmd+s',
+        hotkeyVisible: false,
+        callback: doSomething
+    });
