Auto Highlight on Tab

When customers are doing data entry or bulk price changing, using tab to jump between fields does not automatically highlight the existing text in the field.  If someone is going to be updating pricing in bulk or simply making changes to existing items, you need to use your mouse to highlight the text that is already in the space which either requires several extra keystrokes or using the mouse to highlight the text before pressing delete, then entering the new data.

If the fields auto-highlighted the current text, it would make menu changes MUCH more efficient.
