+/* INTERNATIONALIZATION:

+

+The OMRON R5 contrib added the following action to the old TextTr:

+

+	Ctrl<Key>backslash:	reconnect-im()

+

+This is needed when the im is killed or otherwise becomes unreachable.

+This keystroke is evil (inconvenient, hard-to-remember, not obvious)

+so I am adding one more translation:

+

+	<Key>Kanji:		reconnect-im()

+

+The Japanese user typically hits their Kanji key when they want to do

+input.  This merely makes sure the input is connected.
