I can't seem to find out how to bring up the options menu in order to save, or access other commands. The escape key does not work, and I have hit every key on my keyboard. What am I missing?

I'm using Exult so the keybindings could be a little different but the 's' key should bring up the save menu.

Nevermind, I figured it out. S key brings up a menu - click in an empty text box and type a save name, hit enter and its saved.

For mouse only, just click on the disk icon in your character menu.

Didn't know you can just type s. Excellent.
