Many thanks again for your code.
Actually, manual typing of the function names to record or review plots 
is not a practical solution for me.
I taught it would be a quick task to program Function keys for this purpose.
I uselessly spent time messing with a  "<home>.initrc " file.
The only solution I found is to write the functions names, via Bash 
menu   Settings>ModifyProfile>Input,
in the "Output" column of a new Console:
F10+AnyModifier  : source("/.../GraphicsHistorySubstitute.R")'   ##  
initialise
F10-AnyModifier    :  rp$record()\n            ## record current plot'
F11-AnyModifier    : rp$showPrevious()\n ## show previous recorded plot'
F11+AnyModifier  : rp$showNext()\n        ## show next recorded plot'
F12-AnyModifier   : rp$restore()\n             ## show last recorded plot'
Do you know if and how to achieve the same effect writing a script 
instead of interactively coding key functions?
Thanks for caring, Roberto Scotti

Fantastic!
I just finished answering to Dr. Michael A. Rutter and was imagining of
setting up a procedure using record/replay-Plot.
Yours is far more advanced, many thanks (also for closing question 2)
