This is not so much a bug report but a workflow improvement request. I'm not sure quite how it happens but I often find I have inadvertently left the cursor in the right-hand panel in either Keywords List, Title or Caption. To change views I will hit either E or G or X for deletion. The result is that I get random Es, Gs and Xs thrown into the right-hand panel fields. I occasionally get a Titles replaced by just "g". More frequently, I get duplicated keywords with the addition of "e", "g" or "x" at the end. I then have to clean out the keyword list. I know this could be avoided if I took more care but it shouldn't be such a trap. I'm sure a little more thought by the designers would get around this.
