[OS X TeX] L/R arrow keys don't page up/down in TeXShop 2.03?

[Greg Starr]

I just installed TeXShop 2.03 on a new PowerBook (running OS X  
10.4.2) but I cannot get the expected behavior from the L/R arrow  
keys.  I'm used to having them page up/down (within a single page)  
which is very convenient.  Now (as long as the horizontal scroll bar  
doesn't exist) they don't seem to do anything.

I've changed every conceivable preference to no avail.  I know this  
is a pretty mundane question but I'd sure appreciate any help.  The  
page up/down function of the arrow keys is something I'm quite used to!
