Hi, Philip

Thank you for the quick response.

I have tried auto-revert-mode before, it seems this function only revert files 
being opened in buffers. however, "open-gcal-agenda" is a command or function, 
but not a file opened directly, so auto-revert-mode does not work in my case.

I guess the process may like
1. catch system event of "file updated"
2. find buffer
3. invoke the command in the buffer

Maybe I need to read auto-revert-mode source code, try to find something useful 
and hack it.

Thank you.
