I'm retired now, but I used to carry a laminated half-A4 size card detailing:
Side 1
B757/767 engine malfunction during cruise
Side 2
initial actions for fire and smoke drills
pre-ditching and post-ditching essentials
CB location for aural warning and stick shaker
The rationale was that these situations might require an expeditious response before the relevant QRH check list could be unearthed, particularly if one pilot was away from the flight deck. If I left the flight deck I would ask the copilot to clip the card to his wheel, 'just in case'.
In the case of ditching the card summarised the most important factors to be considered during what would be a very stressful situation.
Many years ago a 757 came to grief after taped-over static ports gave erroneous instrument readings to the pilots. At one stage the crew were getting simultaneous overspeed warnings and stick shaker operation, which probably distracted them sufficiently to lose situational awareness. Tripping the relevant CBs might have been helpful.
The info was printed on an A4 sheet which was then folded in half and laminated. If it's of any use to anyone now, it can be found here as
