   * The main thumb buttons are spaces when tapped and enable the LOWER layer
     when held.
   * Vim style arrow keys.
+  * Left Control is ESC when tapped.
   * Left and right ALT in case you need different behaviors. (For example, the
     default Option and readline's Alt behavior in macOS.)
 * The LOWER layer has mostly meta keys.
