Understanding the Dual-Pane Interface

Master the classic dual-pane file manager layout that makes Captain's Deck so powerful for file operations.

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

Quick reference for F1-F10 function keys:

F1HelpF6Move
F2RenameF7Make Directory
F3ViewF8Delete
F4EditF9Visual Diff
F5CopyF10Quit

Switching Between Panes

The active pane is indicated by a highlighted border. Switch focus with:

  • Tab - Toggle between left and right panes
  • Click - Click anywhere in a pane to activate it (optional setting)

Tip: Enable "Click to Switch Panes" in Settings > General if you prefer to activate panes by clicking, in addition to using the Tab key.

Navigating Files

Captain's Deck supports both Vim-style and traditional navigation:

Selecting Files

Select files for batch operations:

  • Space / Insert - Toggle selection on current file and move down
  • Cmd+A - Select all files
  • Cmd+Option+I - Invert selection
  • Shift+navigation - Extend selection while moving

Selected files are highlighted. The status bar shows the count and total size of selected items.

Note: Selection persists during navigation - arrow keys and other cursor movements do not clear your selection. Press Escape to clear selection explicitly.

Quick Filter

Press / to activate the quick filter. Type to filter the current directory view:

  • Only matching files are shown
  • Press Escape to clear the filter
  • The filter is case-insensitive

Showing Hidden Files

Toggle hidden files (dotfiles) with Cmd+. (period).

Sorting

Click any column header to sort by that column. Click again to reverse the sort order.

View Modes

Switch between different view modes using the View menu or keyboard shortcuts:

  • Ctrl+Cmd+1 - List view (default, shows detailed columns)
  • Ctrl+Cmd+2 - Icon view (thumbnail grid)
  • Ctrl+Cmd+3 - Column view (Miller columns)

You can also access these from View > View Mode in the menu bar, which is useful when the toolbar is hidden (e.g., in Norton Commander theme).

Trackpad Navigation

If you have a trackpad, use gestures for quick navigation:

  • 3-Finger Swipe Right - Go back (same as h or Backspace)
  • 3-Finger Swipe Left - Go forward

Note: Requires "Swipe between pages" enabled in System Settings > Trackpad > More Gestures.

The Terminal Panel

Press ` (backtick) to toggle the integrated terminal at the bottom of the window. The terminal automatically syncs to the active pane's directory.
