+# Comments start with a # sign, do not use them mid-line.
+# Each line must be blank, a comment, or a key definition.

+# key definition: <action name> <key1> [<key2> [<key3>]]
+#
+# Each <key> is an X11 keysym (as output by xev) with optional modifier.
+# For instance, C-x would be Ctrl+X, or 4-space Mod4+Space

+# Same for image navigation ...
