deleting characters on raster's keyboard

[Robin Paulson]

ever since i've had my freerunner, i've had problems using raster's
keyboard (the one with dictionary lookup).
the biggest issues are the swipes for space and backspace - each time
i try to do either of them, i generally unintentionally press a
letter. deleting one character usually becomes very frustrating,
selecting then trying to delete unwanted letters.

i assume i'm doing something wrong - is there a technique for doing
this well? it's intensely frustrating to use

it's got to the point where i want to ditch the thing and go back to
my hideous panasonic, which despite it's many failings at least it
usable for typing

cheers
