Interface & basics

Everyday UI regions and habits.

Main layout

Area	Role
Sidebar	Bookmarks, layouts, quick search, and more
Tab bar	Switch tabs; + creates a tab
Nav bar	Path breadcrumbs, back / forward / up
List	Current folder contents; switchable views
Footer	Status and temporary tools (e.g. batch rename)
Command palette	Global commands and settings

Selection & checkmarks

• Click to select a file or folder; arrow keys move focus.
• Space checks / unchecks the focused item.
• Ctrl+A selects all visible items.
• Many file actions apply to the checked set; with nothing checked they usually apply to the focused item.

Copy, move & delete

Action	Default (Windows / Linux)	Notes
Copy	Ctrl+C	App + system clipboard
Cut	Ctrl+X	Moves on paste
Paste	Ctrl+V	Into the current folder
Undo	Ctrl+Z	Recent paste / cut-move, etc.
Delete	Delete	To Recycle Bin (undoable)

On macOS, copy / cut / paste / undo use ⌘; delete defaults to ⌘+Backspace.

Rename

• Single item: F2
• Batch regex rename: Ctrl+F2 (checked set; otherwise the focused item)

Batch rename previews new names in the list before you confirm.

Filter & search

• Ctrl+F: focus the pane filter (visible items in the current folder).
• Alt+F: focus sidebar quick search (recursive filename search across open tabs).

Layouts (named workspaces)

The sidebar Layouts group saves the current split + tab scene as a switchable workspace:

• Leaving a layout auto-saves it; switching back restores what you left.
• Save as, create blank, rename, or delete layouts.
• The window title shows the active layout name for taskbar recognition.

Session restore

On a normal quit, tessoa saves the workspace (splits, tabs, folders, views, sort, and more) and restores it next launch. If a folder no longer exists, you get a missing-path notice and can navigate away manually.

Preview

Image and text previews are supported; PDF preview is available in builds that include it. Exact capability can vary by version and platform.
