manual/include/common-region-edit-operations.html

<p>
  This section covers a set of <dfn>region editing operations</dfn>
  that are likely to be used often while working on a session.
  Depending on work habits (and experience of other
  <abbr title="Digital Audio Workstation">DAW</abbr>s),
  some of these operations will be critical while others are used only rarely.
</p>
<p>
  All of these operations can be carried out from the keyboard (see
  <a href="@@default-keyboard-bindings">Default Keyboard Shortcuts</a>
  for a list). Equivalent operations can be performed with the mouse
  in most cases.
</p>
<p>
  Some of these operations make use of <a href="@@edit-point-control">the edit
  point/range</a> and <a href="@@which-regions-are-affected">affect specific regions</a>.
