A more thorough explanation:

Motion of course refers to a request made by a party to the court that can be granted as a matter of routine, without further investigation or inquiry.

For example, a motion to extend the deadline for filing a document may be considered a motion of course if it is granted routinely without any further inquiry.

Another example of a motion of course is a request to reschedule a hearing due to a conflict in the party's schedule.

These examples illustrate that a motion of course is a simple request that can be granted without any further investigation or inquiry by the court.
