 .SH DESCRIPTION
-ir\-keytable is a tool that lists the Remote Controller devices, allows one to
-get/set rc keycode/scancode tables, set protocol decoder, test events
-generated by a rc device, and to adjust other Remote Controller options.
+ir\-keytable is a tool that lists Remote Controller devices, loads
+rc keymaps, tests events, and adjusts other Remote Controller options.
+.PP
+Rather than loading a rc keymap, it is also possible to set protocol decoders
+and set rc scancode to keycode mappings directly.

 Note: You need to have read permissions on /dev/input for most of the
 options to work.
