Keyboard and Mouse Interaction

• Pane and nav focus switches on click: To move keyboard focus to the nav pane (favorites, tree, browse history) or Pane A / Pane B, click the target area with the mouse, or use Tab or ←/→ on the keyboard.

  Hovering (just moving the mouse over) does not move focus, ensuring operations target the intended pane.

• Focus to list: When Pane A or Pane B has focus but the file list does not (e.g., immediately after startup or after clicking a tab or toolbar), pressing arrow keys, Enter, Delete, F2, or similar keys moves focus to the list and the pressed key takes effect immediately.

  When focus is on the path input field or search box, key input is used by those fields as usual.

• Mouse interference prevention during keyboard operation: When keyboard operations begin (arrow keys, Enter, shortcuts, etc.), the app automatically enters "keyboard operation mode" and the mouse cursor is hidden.

  During this time, hovering the mouse over the list or nav pane does not move selection or focus (preventing accidental focus jumps to items under the mouse cursor).

• Automatic return to mouse operation: During keyboard operation mode, physically moving the mouse approximately 3 or more pixels from its previous position automatically restores the mouse cursor, returning to normal mouse operation.

  A dead zone prevents recovery from slight vibrations. Opening modal dialogs (like the rename dialog) also auto-restores the cursor when window focus changes, allowing mouse operation within the dialog.
