The sidebar

Toggle the sidebar with ⌥⌘S, or the toolbar icon. Drag the divider to resize it.

Tabs down the side

The sidebar has several tabs: the file tree, starred notes, themes, and plugins when you have any enabled.

Browsing

Action	How
Expand or collapse a folder	Click the folder row
Open a note	Click it — opens in a tab
New note	+ at the bottom
Delete	− (asks first; hold ⌥ to skip for a single note)
Select several	⇧-click, at any depth
Reveal in Finder	⌥-click, or right-click → Reveal in Finder
Toggle preview lines	The eye icon at the bottom

Folders sort alphabetically; files sort by modification date, newest first.

The preview line shows the first line of content from each note without opening it. Turn it off for a denser list.

Searching

The field at the top searches every note in the vault, not just the visible folder:

• Filenames are matched first, because it is fast
• then file contents
• results replace the tree, sorted by modification date
• a spinner shows while a large vault is scanned — the search runs in the background and the app stays responsive

Clear with the × or Esc.

Note

Sidebar search covers the current workspace’s tree. To search across every file tree at once, use the Navigator.
