<p>
  Ardour has many available commands for playback control that can be bound
  to keys. Many of them have <a href="@@keyboard-and-mouse-shortcuts">default
  bindings</a>, Some of the most used are found below.

  Those keybindings are shown in the corresponding menus. Memorizing at least
  the most frequently used can be a great time saver.
