Returning from the '+' to '>' prompt in command line of R Studio

Question

I know the prompt changes from < to + when the command line in R expects you to complete the current command. Is there a way (say, shortcut key) to immediately terminate the command being written and revert from the '+' mode to the regular console '>'?

Answer 1

Press 'Esc' key will bring you back to the prompt (<). You don't need to type word 'Esc'.
