How to automatically paste today's date with keyboard shortcut? I am on El Capitan OS X.

I want to be able to hit some keyboard shortcut and then have today's date be automatically outputted.

Example:

When I press Option + D, "2016_06_13" is pasted into the text field.

The date would be automatically calculated based on my time zone.

Ideally, I'd like to be able to do this universally. So in Finder, Safari, TextEdit, etc. — not just exclusive to one program.

Having this shortcut would streamline my workflow.

Is this possible?
You could do it with Automator like this:


Create new: Services
Services receives no input in any application
Use the search to find and add action: Run Applescript


Copy and paste the following to the field on the right:





tell application "System Events"
    set _Date to (current date)
    keystroke ¬
        (year of _Date as text) &amp; "_" &amp; ¬
        text -2 thru -1 of ("00" &amp; ((month of _Date) as integer)) &amp; "_" &amp; ¬
        (day of _Date as text)
end tell


Note that the day will not have a leading zero like the month does. If you want that, you could replace the line with: (day of _Date as text) with: text -2 thru -1 of ("00" &amp; ((day of _Date) as integer))




Save with: Cmd + S. Give it a name you can remember in the next step.


If you simply use the Save command ( Cmd + S ) instead of Save as... the Service file is automatically put in the right place.





The Last step would be to define a shortcut for the service you just made.

Go to mac System preferences &gt; Keyboard &gt; Shortcuts &gt; Services and then find the service you saved before. You should find it at the bottom area of the list. Double click the none text on the right side of the service name and give it a shortcut.
