I'd like to make an Input Manager for Safari that can find the

thru Accessibility and the UIInspector, I see a lot of the work is
done; Accessibility can easily get text although I'm not sure if it
can find the specific word under the cursor.
I'm hoping someone can tell me if this is the right approach or if
there is a better method. Thanks for your time.
You're on the right track. What you want to read is the
documentation for
the so-called "parameterized attributes," which were introduced in
Panther
or Tiger's implementation of the accessibility API. They give you
access by
screen coordinates to the text under the mouse, which you can parse by
glyph, word, line, etc. using the parameterized attributes.
To see how they work, download the free 30-day trial version of
PreFab UI
Browser at www.prefab.com/uibrowser, and use it to examine the
parameterized
attributes for a text view in, say, a TextEdit document. UI Browser
lets you
enter numerical parameters and then calls the parameterized attribute
functions to get the result, which is typically shown as the glyph,
word,
line or text block you requested. By default, UI Browser shows you
the line
the mouse was over, but you can code this as you like. UI Browser's
online
Help (under the Help menu) explains how they work.
