Prevent taps while typing?

[nnutter]

I've tried playing with as many of the Tap or Palm properties as seemed plausible. Does anyone know if any of the properties can disable taps while typing? As an example, if I position the cursor at the start of a line I can start typing and then while still typing tap and it continues typing in that new location.
