Text+ Expression Question

I just downloaded Fusion and it's a lot of fun. I'm trying to figure out how to burn the source frame names into the frames. I read I could use this for frame number in the sequence:

"Current frame " .. time

However, I'd really like the .jpg source file name burned in. Also, I'm thinking it should be easy to burn in timecode but I'm having difficulty finding that option as well. Thanks in advance to anyone that has more experience than me!

To get the full path to a file you can use this in a Styled Text simple expression:

Loader1.Clip.Filename

However, since simple expressions can't use all LUA functions I haven't found a way yet to split the path and just show the filename.
