How to invoke rclone config reconnect from the command-line

yeah, no worries!
it's quite difficult as it is to keep track of changes in the docs, let alone enhance the entire user interface.

my suggestion is, roughly, to make sure to have a non-interactive rclone command, for each and every rclone command.

I was, and still am, pretty confused by the rclone docs -- another example of my doubts was How to create new "crypt" remote from command line.
also, if I may be honest, the "global flags" page is not really helpful, because it coalesces stuff together that not necessarily belongs together, and makes the user go there fishing for possible parameters.
it would be a lot more readable if all the flags applicable to a certain command were in its doc page.
IMHO!
