Operation Manual

Working with Text 109
Each frame's story text can adopt its own individual autofit setting as follows:
The AutoFit Options flyout offers three autofit options which
continuously act upon a selected frame's story text.
No Autofit
This is the normal mode of operation where, if selected, text won't
automatically scale throughout the selected text frame, possibly leaving
partly empty frames at the end of the frame sequence.
Shrink Text on Overflow
If selected, extra text added to a selected frame will shrink all frame text
to avoid text overflow.
Autofit
If selected, the frame will always scale text automatically by adjusting
text size (compare to Fit Text which fits text once, with any additional
text causing text overflow).
AutoFlow
When importing text, it's a good idea to take advantage of the AutoFlow feature,
which will automatically create text frames and pages until all the text has been
imported. This way, enough frames are created to display the whole story. Then
you can gauge just how much adjustment will be needed to fit the story to the
available "real estate" in your publication.
If you add more text to a story while editing, or have reduced the size of frame,
you may find that an overflow condition crops up. In this case you can decide
whether to use AutoFit or click the frame's AutoFlow button.
