When using a shell.write command, can anyone help me with the correct syntax for sending a left-arrow keystroke (or right-arrow for that matter) ?
Thanks in advance,
Ralph.
I should have thought to ask my best friend Mr Google first 
For anyone else searching for the same information (for a mode 2 interactive shell), the answer is:
// Left arrow
Shell.write chr(27) + "[D"
// Right arrow
Shell.write chr(27) + "[C"
