	 #'#[257 "\211<\203�\211@\300=\203�\301
\302\"\207\207"

 t)

Documentation

Cause previews to open automatically when entered.

Possibilities are: t autoopens, nil doesn't, a symbol will have its value consulted if it exists, defaulting to nil if it doesn't. An integer will specify a maximum cursor movement distance. Larger movements won't open the preview. A CONS-cell means to call a function for determining the value. The CAR of the cell is the function to call which receives the CDR of the CONS-cell in the rest of the arguments, while point and current buffer point to the position in question. All of the options show reasonable defaults.
