#77 Treo usablity problems

[Anonymous]

Just for the record:

When entering a function, it's really easy to press
Option+backspace on the keyboard. That is the
equivalent to the Cancel. Could you disable that
keypress when entering a function or pop up a dialog
asking "Do you really want to cancel?" or something like
that.

When entering numbers into a matrix or elsewhere, the
status of the option button is not saved between dialog
boxes. I have to tap the cell, transfer stylus to typing
position, press option, enter number, transfer stylus
back to tapping position, press ok, tap next cell, etc.
Option is needed to enter numbers and symbols. It
would be nice if I could lock Option and tap with one
hand, and type with the other.
