How do I change the settings, locate a script or extension so some of the MetaData will automatically populate when a file is saved?

For example

Title = the file saved name...yes I know the there is a space below file name for title...but I am looking for the lazy way :)

Date = last saved date

Keywords = title of words with commas + predefined keywords that I want included

Source = Website

Come on I know someone has the answer :)

Some info can be part of a template. (Persistent stuff like name, website, etc.)

I haven't tried it, but if you are on Windows, auto hotkey scripts could populate other fields with shortcut keys for date/time, window title (filename). One hotkey per form field (not sure AHK can read the form labels).

I presume keywords would be entered on the fly, but maybe could be auto copied from a textfile.

I feel soo old....I dont even know how hotkeys work.....but I do understand the basic ideas - so I am off to get into some trouble with Hotkey.  Thanks for the idea @TylerDurden
