Yeah, Maple's UI design decisions are pretty baffling.
Anyway, we used to have javascript-based syntax highlighting in the
notebook for a little while about a year or so ago, but it just didn't
feel sufficiently snappy so we got rid of it.

Have you tried
Data --> Attach file
you could attach the code from that huge cell as a file, then edit it
that way, and just load it into your worksheet. This might work
better for you, since there is nothing clever going on with the text
editor one gets that way, so it is very snappy. Here's a step by step
tutorial:
1. create a new worksheet
2. Data --> "Upload or create file..."
3. In the box "Or enter the name of a new file, which will be
created:" put "foo.sage" then click "Upload file".
4. Put
def f(n):
return n^2
in the box that you see and click save changes.
5. In your new sage worksheet, type
load foo.sage
or
attach foo.sage
6. Now f is defined.
7. If you click Data --> foo.sage, you get a box where you can edit foo.sage.
Somebody might want to improve the usability of the above, e.g.,
*this* would be a great place to make it possible to use a nice text
editor with syntax highlighting. Like Moinmoin that editor could be
off by default, but by clicking a but one could trivially switch it
on.
