InDesign 1.5 Expanding and collapsing panels

1. In the default dock to the right of the document window, click the Pages panel icon to expand the Pages panel.
Try the other panel icons.
2. To collapse the Pages panel, click the double arrows to the right of the panel names of click the panel icon again.
3. Choose Window > Info to open the Info panel.
4. To add the Info panel to the dock, drag it by its title bar below the Character Styles panel (i.e. the Control panel); release the mouse button when the blue line appears.
Then the Info panel combines with the Tools panel. It seems that we can't separate them without resetting Advanced.
5. Drag the left edge of the panel dock to the right until the names are hidden.
6. To expand all the panels in the dock, click the double arrow in the upper-right corner of the dock.
If you click the double arrow again, the panels collapse back to icons without names.
(No way. Do as step 5 does.)
