This page shows the content of a tree. It is essentially a list of items, each of which consist of a key and a value.
The key is shown in the boxes on the left. It is a triple of a 64-bit id, an 8-bit type, and a 64-bit offset. What each of them means depends on the tree we're in. You can search for a key id by using the search field below.
The value is summarized to the right of the key. To see the value in more detail, unfold the key by clicking on it.
Finally, to the very right, we have the logical address of the metadata node which the item is stored in.
