In plain Windows, the left/right arrow keys can be used to move the text cursor back and forth in the command line buffer to delete or insert characters before the command is submitted.
In the servercore docker image, the left arrow key works the same as the backspace key, deleting the last character, the text cursor is always located at the end of the input line. At least that is how it behaves in my installation.
Is there any way to enable left/right arrow key navigation in the servercore cmd.exe?
The size of cmd.exe is exactly the same in servercore and on my native desktop Windows, They have the same last day modified (Apr. 12th 2018). So I assume that the reason for arrow keys not working is NOT that this functionality has been shaved off to reduce image size!
