With the latest Keynote update before Christmas 2015 it include a new feature.
The feature allows the user to set the case for the title and description of keynotes (as a preference) and to specify exceptions, e.g. all upper-case except for the letters ‘mm’ following a number (so dimensions come out as 100mm rather than 100MM).
Sets these preferences using a new menu item Cadimage > Keynotes > Preferences
For more info on how to use the new feature, head over to the Cadimage Knowledge Base. https://cadimage.zendesk.com/hc/en-us/articles/207356153
