 ### Targeting Windows
 
 AutoSave only sends keyboard input, if a the active window matches a given filter. There are two ways to specify which windows to target:
-* Caption matching (by normally starting AutoSave),
+* Title matching (by normally starting AutoSave),
 * Connecting to another application (by using Connected Shortcuts).

+#### Title Matching

 It's up to the user to enter an unambiguous phrase.
 
 Additionally, AutoSave allows the user to filter windows using [regular expressions](http://simple.wikipedia.org/wiki/Regular_expression) instead of normal text comparison.
