I don't use Think C (I use MPW), but it sounds from your description
like Think C has it right.

Inside Mac says:
------
"Holding down the Command key while pressing an arrow key should move the
insertion point to the appropriate edge of the window. If the insertion point
is already at the edge of the window, the document should be scrolled one
windowful in the appropriate direction and the insertion point should move
to the same edge of the new windowful. Command-Up Arrow moves to the top of
the window, Command-Down Arrow to the bottom, Command-Left-Arrow to the left
edge, and Command-Right Arrow to the right edge.

"The Option key is reserved as a "semantic modifier" key. The application
determines what the semantic units are. For example, in a word processor,
where the basic semantic unit is the character and the next larger unit
is the word, Option-Left Arrow and Option-Right Arrow might move the
insertion point to the beginning and end, respectively, of a word.
(Movement of the insertion point by word boundaries should use the
same definition of "word" that the application uses for double
clicking.) The next larger semantic unit could be defined as the
sentence, in which case Option-Left-Arrow and Option-Right-Arrow
would move the insertion point to the beginning or end of a sentence.
In a programming language editor, where the basic semantic unit is
the token and the next larger one might be the line, Option-Left-Arrow
and Option-Right-Arrow might move the insertion point left and right
to the beginning and end of the line, respectively."

MPW does the following:

Command-Leftarrow               MoveStartOfLine
Command-Rightarrow              MoveEndOfLine
Command-Downarrow               MovePageDown
Command-Uparrow                 MovePageUp
Option-Leftarrow                MoveWordLeft
Option-Rightarrow               MoveWordRight
Option-Downarrow                MoveLineDown
Option-Uparrow                  MoveLineUP

which (to me) seems to be a fair interpretation of Inside Mac. I think
(based on <1 day of use) that WriteNow 3 follows the same conventions.
MS Word (as usual) does its own thing.

Of course, under MPW, the key bindings can be reconfigured to whatever you
like (plug, plug). :-)
