How to use hot keys to Save to PDF in face book

Hi Team

Can any one tell me how to use hotkeys to do save as operation as in below pics.

basically i want to perform Ctrl + s to open file browser dialog box to save.
im trying to save PDF file as HTML file

pls share the commands .

For sending hot keys, you need to use Send Hotkey activity. Then perform clicks on the dialog box to save the doc as pdf.

use alt+shift+f2 or shift +f12

Thanks! for your response, Simply using Hot keys Ctrl + s worked for me, but will try with above keys too.
