Acrobat DC: How to hide panels and see PDF contents

By default, when using the Acrobat DC plugin the tools and navigation panes obscure the contents. To solve this open DC, hide the Navigation pane (F4), and the tool pane (Shift-F4). Then go to Edit->Preferences->Documents and select Remember current state of Tools pane. Those hot-keys also work in the viewer if you prefer to keep the default settings.
