ctrl D is for restart
ctrl E is paste Mode, essentially turns off the auto-indent feature
ctrl A is in Raw REPL mode
Raw Mode
Raw mode is not something that a person would normally use. It is intended for programmatic use. It essentially behaves like paste mode with echo turned off.

Raw mode is entered using Ctrl-A. You then send your python code, followed by a Ctrl-D. The Ctrl-D will be acknowledged by ‘OK’ and then the python code will be compiled and executed. Any output (or errors) will be sent back. Entering Ctrl-B will leave raw mode and return the the regular (aka friendly) REPL

uos.listdir()
uos.mkdir(‘myDir’)
uos.chdir(‘..’)
uos.rmdir(‘myDir’)
