When doing a C-h v the Help buffer shows the value of the variable and also<br />
its documentation.<br />
<br />
Bind the currently unused key &#39;e&#39; to edit the variable&#39;s value, maybe in a separate popup<br />
buffer if the value is complex. E.g. the user presses e, the value pops up rendered in<br />
editable lisp format, the user edits it in place, presses C-c C-c and the variable is set<br />
to the new value.
