+# The default hotkeys are adjusted for the QWERTY layout.
+# If you want to change them, please follow these steps:
+#
+#   1. if you map key X to key Y, make sure that key Y is not
+#      mapped twice and remap the old mapping.
+#   2. if you change key combinations, like "dd", please adjust
+#      the key_combinations function. Search for the function
+#      and you'll find detailed instructions.
