Short description of error
Official documentation claims that pressing CTRL+C will copy a ruler's value.
I was unable to reproduce this result.
Exact steps for others to reproduce the error
Failure 1 (Edit mode):
Create any mesh object.
type t to open the tools.
Select measuring tape tool.
click close to a vertex to snap the measuring tape's first point to it.
hold CTRL and click near another vertex to measure the distance between them.
You get measurement.
Attempt to paste this value in a field. It will fail regardless of what mode you are in.
Failure 2 (Object mode):
Verify that this fails in object mode as well by measuring any space in object mode and as soon as you see the measurement, press CTRL+C. Attempt to paste this value in a field. It will fail.
