Focus on a Container or Field
Focusing dims everything that is not connected to what you picked, so a single flow stands out on a dense graph. It changes only the view: nothing is added, removed, or saved.
Steps
Step 1: Click the header of the node you want to isolate. It becomes the active selection.
Step 2: Every node and connection that is not part of that container's lineage dims, and the connections running through it stay at full strength.
Step 3: Press Esc or click the canvas background to clear the focus, or click another node to move it.
Step 1: Expand the field list on the node holding the field. Fields that take part in at least one field-level connection carry a lineage indicator, which is the fastest way to find them.
Step 2: Click the field row. Every connection that does not touch that field dims, across the whole visible graph, not only on the node you clicked.
Step 3: Click the same row again to turn it off. Pressing Esc or clicking the canvas background also clears it, and clicking another field moves it.
Step 1: Click More options on the toolbar at the bottom left of the canvas.
Step 2: Choose Focus current to return the view to the container whose Lineage tab you are on, or Focus selection to centre on what you have selected. Focus selection is greyed out while nothing is selected.
