Renaming items. Pre-fill text boxes with existing names?

[MBlazerGuy]

Hi,
When an item is renamed, the text box is always blank.
Often when naming something, there could be type-o's, and you have to type in the entire names again.

Could you please enter in a very simply bit of code that would pre-fill the text boxes for Renaming, and anywhere else text boxes are used, with the current existing names, so they can be easily changed?

Thanks, Doug
