Older game - The Journeyman Project 3

I just downloaded this game from GOG.com. I need some help regarding the game menu etc. How do I save a game, use inventory and exit the game. I have tried the usual Esc.key etc. but that doesn't seem to work. Thanks for any help...

Linda,

Download the manual from replacement docs.com here.
It should tell you the particulars.

Thank you for the quick response!
