Selection And Search

Selection

Ctrl+Click	Add to or remove from the current selection
Shift+Click	Range-select from the last-clicked item to this one

Selecting items in SecondBrain updates Unity's own selection (Inspector, Project window) in sync.

Selection is cleared automatically when you navigate to a different node.

Search

Type in the search bar at the top of the toolbar to filter the tree in real time. Search is:

• Case-insensitive
• Substring match — matches any part of a node's name
• Universal — searches Containers, asset references, and Action Items

Input	Result
Down arrow (in search bar)	Move keyboard focus to the first matching result
Enter (in search bar)	Exit search mode; keep the current filter
Escape	Clear the search and return focus to the tree

The search text is preserved through tree refreshes during the same editor session.

Search Filter

Click the filter button (funnel icon) beside the search bar to open the Search Filter popup. It lets you restrict which node types appear in search results.

Available filter flags:

Flag	What it includes
Containers	Container nodes
Scene Objects	Scene Object references
Scenes	Scene asset references
Text Assets	Text file references
Scriptable Objects	ScriptableObject asset references
Prefabs	Prefab asset references
Assets	All other asset references
All	Everything (equivalent to all flags enabled)

The default filter includes all types except Containers, keeping results focused on leaf content. Toggle individual flags to narrow the search to just the types you care about.

The filter button is highlighted when a non-default filter is active, so you can see at a glance that results are being restricted. Your filter choice is saved in EditorPrefs and persists between sessions.
