Apologies for this OT posting but I posted on a couple of other sites more 
related to the following question but haven't seen a reply and feel sure 
there are iPhone or iPad users here who will know.

Has anyone developed a quick reference chart where the action of a given 
gesture
precedes the gesture?  For example, To turn speech off or on, perform a 
three finger double tap. If one  exists, I won't need to do one in braille 
or large print for quick reference as I still forget now and then.

Thanks!
