This macroscript lets rename the selected object without switching to Modif-Panel. Handy - if you have to rename a lot of objects without a common name-structure.
To use it - go to Maxscript / Run Script and pick this file.
You will find it in the 'rdg::preset' category of Customize -> Customize User Interface. and you'll be able to assign the script to a quadmenu - shortcut key - etc.
Look for the script titled 'quickrename selected object'.
Assign a shortcut and voila - you're done!
