-    * I'd like to insert more hotkeys to make logisim-evolution more fun.
-  * Such as press *SPACE* to rotate the component to be placed on.
+    immediately.
+  * Also, after modified more classes, which can be clearly
+    viewed in the FILE CHANGED, I added 26 other hotkey bindings, supporting changing the hotkeys
+    for component rotation/direction, auto-labeler and gate-modifier.
+  * With more options added, I use JScrollPane to get them all in.
+  * And there are some important key bindings that have clear meanings
+    and are accepted by nearly each person, I set them as uneditable.
+  * However uneditable, people can treat this tab as a 
+    key-binding reference.
+  * In addition, I'd like to insert more hotkeys to make logisim-evolution more fun.
+  * Such as press *SPACE* to flip a splitter or transistor, 
+    getting their image along the Y axis.
 
 * @dev (????-??-??)
   * Added support for scanning 7-segment display on FPGA-boards
