One liner of the week:
write/lines %hist.r head reverse copy rebol/console/history
Takes the history of input into the console and prints it out, line by line, to a file. This way you can paste in functions and whole scripts, and save them for viewing and editing. Sorts it to display the oldest commands at the top.
