 Abbrev Table Properties Like abbrevs, abbrev tables have properties, some of which influence the way they work. You can provide them as arguments to define-abbrev-table, and manipulate them with the functions:   Function: abbrev-table-put table prop val
 Set the property prop of abbrev table table to value val. 
  Function: abbrev-table-get table prop
 Return the property prop of abbrev table table, or nil if table has no such property. 
 The following properties have special meaning:   :enable-function 
This is like the :enable-function abbrev property except that it applies to all abbrevs in the table. It is used before even trying to find the abbrev before point, so it can dynamically modify the abbrev table.   :case-fixed 
This is like the :case-fixed abbrev property except that it applies to all abbrevs in the table.   :regexp 
If non-nil, this property is a regular expression that indicates how to extract the name of the abbrev before point, before looking it up in the table. When the regular expression matches before point, the abbrev name is expected to be in submatch 1. If this property is nil, the default is to use backward-word and forward-word to find the name. This property allows the use of abbrevs whose name contains characters of non-word syntax.   :parents 
This property holds a list of tables from which to inherit other abbrevs.   :abbrev-table-modiff 
This property holds a counter incremented each time a new abbrev is added to the table.
