Safari does use sentence granularity in accessibility code. But it‘s also
available through the Mac OS X WebKit API and can be tied to the Cocoa key
bindings system by expert users. This set of selectors:
- (void)moveToBeginningOfSentence:(id)sender;
- (void)moveToBeginningOfSentenceAndModifySelection:(id)sender;
- (void)moveToEndOfSentence:(id)sender;
- (void)moveToEndOfSentenceAndModifySelection:(id)sender;
- (void)selectSentence:(id)sender;
is available for use in both Objective-C and in a key binding dictionary, which
can bind a key to one of these operations.
