Based on Sjoerd's interesting solution and other comments, I made a
few variations which I found useful, so I share them with you.

The following function "Inspect" accepts a context and displays a grid
with expandable definitions, more or less suitable for copying and
pasting (some care must be taken with strings).
Moreover, in case a subcontext is present (like e.g. `Private`), which
may make internal variables less readable, this context may be
provided as a second argument so that it disappears as a prefix from
the definitions.

The function does not contain Refresh anymore so that it allows
exploration of contexts like FE`.

Perhaps, experts about Dynamic interaction, may actually do better.
