Hi cc
Here's what I do (on a copy of the presentation) after having watched it
through completely (normally accompanied by 'oh no, no, no, no's and sharp
intakes of breath etc):
1. Set up the master as I actually want it to be
2. Look at format -> replace fonts to see what's in there at the moment (may
not actually change fonts yet)
3. On each slide select the layout I need then hit 'reapply layout' (from
the drop down on the slide layout thumbnail). Sometimes a couple of times
until it sticks.
4. See where that has got me. If there is lots of stuff in text boxes I may
copy & paste into placeholders or I may not - depends if the file is being
updated for a one-off or if it will be edited again in the future.
5. If there are autoshapes I make one how I want then use the 'pick up
object style' and 'apply' buttons.
6. Review & tweak.
7. Bill client & train on use of placeholders
It really depends on the file... Oh, there is a style checker but I've never
got on with it very well. Other people may have more efficient ways of doing
this but I find automation sometimes gives unexpected results (and I like to
be in control).
Oh, and I forgot to mention animations - if they have used different ones on
every slide I remove & add animation to the master placeholder.
As I said every file is different. But I hope that gets you started.
