The Orthodox File Manager Philosophy

Captain's Deck follows the "orthodox file manager" design pioneered by Norton Commander in the 1980s. This two-panel layout shows source and destination side-by-side, making file operations intuitive and fast.

  • Left Pane: Source or working directory
  • Right Pane: Destination or comparison directory
  • Active Pane: The pane with focus (highlighted border)

Interface Layout

Top: Tab Bar

Each pane can have multiple tabs, letting you keep several locations open:

  • Cmd+T - New tab in active pane
  • Cmd+W - Close current tab
  • Cmd+] / Cmd+[ - Switch between tabs

Middle: File Panels

The two file panels show directory contents with columns for:

  • Name (with icon)
  • Size
  • Date Modified
  • Permissions (optional)

Right-click any column header to show/hide columns.

Bottom: Function Key Bar
