Problem with editing in 'List Replace' method

I LOVE the changes that were made in the newer versions of AR for this method. The new buttons, especially the 'Item Details' button are much welcomed!
The only problem that I have with the editing is :
- When under the main Renaming methods button, and in the left 'Replace' column - if I move to the end of the line (right-most character) and move one more, the cursor automatically moves to the 'Replace With' column. Is there an option to turn that off and on? I guess I can see how some people might like that behavior, but very often I paste a value into 'Replace' and then use the cursor to button to de-highlight the pasted text, which then moves the cursor to the next column.
