Selection And Search
| Input | Result |
|---|---|
| Click | Select one item; deselect everything else |
| Ctrl+Click | Add to or remove from the current selection |
| Shift+Click | Range-select from the last-clicked item to this one |
| Ctrl+A | Select all currently visible rows |
| Up / Down arrow | Move selection one row |
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.
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.
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.
