Let's say one forgets the number of turns a scenario is scheduled for during and/or they'd like to re-read about the scenario again during game play. How does one access that information?

Scenario briefing:
Stop. Save & Exit.
Goto scenario page click on scenario listing and re-read scenario details. Exit.
Reload saved game and continue.

Game Length is of course displayed in the info bar at the bottom right.
Look for Length : XX
