How to identify where a particular block come from? I have to modify a block that appears on the home page of the website, that I did not make myself. The block appears in admin/build/block with the title "Block Title (nodeblock)", so I assume that this has  been created by the nodeblock module, but I can't find where I can edit this content.

Can someone help me to find the right administration menu to view and modify this nodeblock content ?
The easiest way for Drupal 6 would probably be to use the Contextual links module.


  Hover over nodes, blocks, and views blocks to expose styled
  edit/configure/delete tabs.


It's a backport of the same functionality that is in D7 core, but for Drupal 6.

Just hover over the block on the front page, and hit edit to edit that particular block.
