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)
