There has been various threads about auto updating callouts throughout a file with general agreement that this isn't possible except kind of using a database.   As an experiment I've created a "Housekeeping"  worksheet for callouts where I can change the text of a callout/keynote straight from the worksheet. So by summarising the "Text" column I can then edit the text of mulitiple callouts at one time. I'm using a field called 'Callout'.'Text'.   I am wondering if anybody has tried this in practice and if there are anybugs? So far it seems to be ok...
