See attached diff file. Patching PyShell.py Version 1.2.1

PyShell ignores letter/number key presses when the cursor is not on the
command line. Instead it should redirect any letter/number key presses
to the command line. (Changed ModifiedUndoDelegator)

Also, up/down arrow presses should scroll through history when the
cursor is on the command line. But when the cursor is not on the command
line, the arrow keys should move around the PyShell window. (Added new
bindings with conditional logic)

I like the two changes: jump to command line and scroll previous command
lines without having to search back up through the output.  Just don't
imitate the Windows terminal too closely with its inability to just
select previous output (without Symbol/Edit/Mark).

Hi Terry,

The patch allows you to select previous output if your cursor leaves the 
command line area. Press the left arrow button at a new command line 
does this.

Thank you for your feedback!

Thanks for the patch, I'll look at it.

In the future, please send unified diffs (-u), not plain diffs.
