Identifying the source code & what file it's in?

Is there an easy way to figure out what files are applied to each page in cs cart? Updating the code is not a problem, but finding the code to update seems to be the hard part. I’m looking to make some changes but having trouble figuring out what files I need to update. I appreciate any help anyone can give me on this one.

You can start by viewing your store in customization mode to enable it go to admin ->design ->design mode->enable customization mode,

You’ll see a small icon in the upper left corner of each major object (block, column, etc.). Click it and it will give you a list of templates. Hovering over one will highlight the area the template applies to (most of the time). Clicking the template name will put you into the template editor.

Worked great. Thanks for the reply guys.
