If in Insert, Replace or Visual mode put a message on the last line. Use the 'M' flag in 'highlight' to set the type of highlighting for this message. When |XIM| may be used the message will include "XIM". But this doesn't mean XIM is really active, especially when 'imactivatekey' is not set. NOTE: This option is set to the Vi default value when 'compatible' is set and to the Vim default value when 'compatible' is reset.
