How do I switch to the Feature mode in Cisco ASA 5505 ASDM?

I'm trying to set up a site-to-site VPN on my ASA 5505.  I used the VPN Wizard within the ASDM to create the site-to-site VPN, but I'm fairly certain I made some errors in the process.  I'd like to fix those errors, but the VPN Wizard panel displays this message:  

"Only new VPN configurations can be created using this wizard.  To edit an existing configuration, switch to the Feature mode and select VPN."

I'm not a Cisco expert, and, although I've used the command line interface, I prefer the ASDM.  But I have no idea what this "Feature mode" is.  How can I switch to Feature mode?  (Or by "Feature mode", does Cisco mean I should be using the command-line interface?)

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I think with feature mode they just mean to go to the vpn tab in adsm and open the specific features you want to edit.
