Cannot find physical script accordance of T3D components

I am new to T3D. One of my biggest challenges for customizing T3D is that I need to quickly find the script accordance of functions and objects I am using and interacting with them in world editor. For example, in world editor I encounter a function such as Canvas.setContent(...) and want to find the physical location in the scripts that this function has been firstly defined. Currently, I open the T3D project in torsion and use "find in files" to find a math of functions or whatever I am looking for. However, this is time consuming and also naive. Could someone please let me know how is it easier to find physical location of the things like functions in T3D scripts. I have also reviewed t3D script manual but it didn't help me as it introduces the logical categorization of T3D components. Thanks in advance.
