I am about 3 hours into the Visualforce Developers Guide. One copy and past code allows you to create tabs for your related lists. I would like to use this in our live production but where do I find the apex names for these objects?

Section of the code:

<apex:tab label="Notes and Attachments" name="NotesAndAttachments" id="tabNoteAtt"> <apex:relatedList subject="{!account}" list="NotesAndAttachments" /> </apex:tab>

  I want to add a custom object to my tabs

Where do I find the tab id? In this example the id is "tabNoteAtt". How can I find this for my custom objects?

Thank you in advance
