Automator, Rename Service

Hello,

im wanting to add a service to automator,

just a simple 'rename' service.

the reason I'm having difficulty, and are asking mac rumours,

is because everytime i google for help, i come across a page, that tells me step by step how to rename BATCH files,

all I'm after is a step by step guide, on how to rename just one file, or one folder, by letting me input the txt straight into the item itself.

not by opening a window or anything, just directly into the icon, for example when you create a new folder, it allows you to do this.

many thanks in advance,.

Stuart
