UPDATE:
It appears from a quick look at the module source that nodeblock
uses the node's nid as the block delta.
So, from admin/build/block
if you click on the configure
link on the block in question, it should take you to something along the lines of admin/build/block/configure/nodeblock/###
. That trailing ###
is the nid of the node in the block. So then off you go to node/###/edit
.
OTHERWISE:
If this is just a one-off thing, a quick look at the default node-nodeblock-default.tpl.php
template for creating these blocks shows...
<div id="node-<?php print $node->nid; ?>" class="node<?php if ($sticky) { print ' sticky'; } ?><?php if (!$status) { print ' node-unpublished'; } ?> clear-block">
...so I would just surf over to your home page, and then take a peek at the source generated in your browser, and there it should show a <div>
wrapping this block with an id
of node-###
.
Then, going to node/###/edit
should take you on your way.
