total mess at mapping controls

[el0375]

hello, i notice that i am a mess mapping the controls for ClOD, mainly because are too many and that for some i dont have need to use them most of time/ use them on specific moment. so i ignore their existence.
however now that i trhow myself into full realism i am forced to use them. it's got a mess for me.
what you usually do for mapping so many controls? and to remember them more or less , what pattern, what functions etc?advice, suggestions?
