If you've got a MACRO-enabled pointer/scrubber device, how about a One-Click-Solution back to the Timeline and Play On. I have the CSP, which after 5 years, I've figure out how to create MACROS and here that is one that gets me back to the Timeline from ANY Vegas Control: P/C, FX, Trimmer etc.
If anybody wants the MACRO Layout, I'll post it here.
