Please, please provide a way to cancel quickfill on a per-transaction basis

[Paul Abrahams]

I like Gnucash, but it's maddening what I have to do to get rid of a 
transaction split caused by quickfill from the previous transaction.  I've 
tried adding a space after the description field, as someone once suggested.  
That works once, but then the name followed by a space is memorized also.  

It's not good design to force a user to switch focus from keyboard to mouse 
and back again unless it's absolutely necessary.  There's no easy keyboard way 
to get rid of the split.  Even Alt-N/v doesn't do it because V in that context 
is listed both for RemoVe Transaction Split and Void Transaction.  And that 
still would be far more keystrokes than needed.

Having a backspace at the beginning of the description kill quickfill for that 
transaction would solve the problem neatly without in any way inconveniencing 
the use of quickfill when it's wanted.

My observation is that for some payees the account is the same almost all the 
time, like a gas station, and for others it's almost always different, like 
Walmart or Costco.
