Comment 1 for bug 1164973

The current implementation of "C" is working like "undo" on a word processor. Backing out of a transaction.

This is somewhat unexpected, and I'd like some input from design as to exactly how C should behave.

Currently (11 April, daily image):-

Press 2 + 2 =

Screen shows:-

  2
+ 2
---
  4

When you press "C" the display changes to:-

  2
+ 2

On a traditional calculator the C key usually clears what is on display, it doesn't undo the last transaction. Can design weigh in and give us some guidance on what it "should" do?
