I once investigated the BAT one-hand keyboard for a client.  I experimented
with it briefly and determined it to be very functional.  If I needed to
type with one hand, I would chose this method over a QWERTY keyboard.

Here is some information from the manufacturer's web site:

BAT Personal Keyboard
We've single handedly improved the way you'll use your computer with the
BAT(tm) Personal Keyboard. A one handed, compact input device that
replicates all
the functions of a full size keyboard, but with greater efficiency and
convenience.
Surf the net with blazing speed and no repetitive typing; use the BAT
alongside a graphics tablet and get twice as much done; or simply have fun
with the
hottest new concept in keyboard technology.
The BAT is easy to learn and use. Letters, numbers, commands and macros are
simple key combinations, "chords," that you can master in no time. Best of
all
the BAT's unique ergonomic design reduces hand strain and fatigue for
greater comfort and productivity.
The BAT is the ultimate typing solution for persons with physical or visual
impairments and is proven to increase productivity when used with graphic or
desktop publishing software.

Hi,
Our service put together a handout on using the keyboard one handed - might
be of use to you - I've attached it. Some people with CP who I've see at our
assistive tech service have had difficulty with movement coordination and
organisation, limited awareness of where their fingers are/how far their
fingers are moving when they can't see them in the less affected hand. this
has mdae touch typing slow and effortful, with a heavy reliance on searching
for keys visually. For people not able to see the keyboard we have used
tactile markers on specific keys and at the beginning of rows - particularly
when they are first learning the layout of the keyboard.
Depending on the quality of movement, a compact - laptop sized keyboard has
suited some people. If coordination is more difficult larger keys - such as
those on a Big Keys www.bigkeys.com keyboard or a programmable expanded
keyboard eg Intellikeys www.intellitools.com might be useful.
Anyway, hope some of this is of use,
