This relates to WP Version 3.
I'm attempting to create two lists for a sidebar, each list would be selected by a link category.
The codex suggest I can do this by using
wp list bookmarks
with a link category argument
(string) Comma separated list of numeric Category IDs to be displayed. If none is specified, all Categories with bookmarks are shown. Defaults to (all Categories).
However, when I look at the table of Link Categories I don't see any ID.
How does this work, or where is there a reference that explains how to build the code snippet to accomplish a list based on list categories.
