+	redefining existing keyboard shortcuts to operations and creating new ones.

+
+<h2>Contexts and Subcontexts</h2>
+
+<p>
+	The important concept to understand here is that the same shortcut can be
+	used for different operations in different contexts. E.g. in the
+	<dfn>Editor</dfn> context, the <kbd class="button">T</kbd> key switches
+	on the <dfn>Stretch</dfn> mode to time-stretch clips on the canvas. However,
+	in the MIDI Step Entry context, <kbd class="button">T</kbd> inserts
+	an F-sharp note. The contexts are represented by tabs in this dialog, e.g.
+	Editor, MIDI, Recorder, etc.
+</p>
+
+<p>
+	Inside every tab, features are grouped into <dfn>subcontexts</dfn> that can
+	be expanded or collapsed by clicking the triangular-shaped button to the
+	left of the name of each subcontext. E.g. the 'Snap' subcontext lists all
+	snapping units, while the 'Region' subcontext lists all actions accessible
+	via the right-click menu.
+</p>
+
+<p>
+	The <dfn>Search</dfn> function at the bottom of the dialog works within
+	the currently selected context/tab only. If a search returned zero results,
+	switching to a different context is a viable solution to locating the action
+	of interest.
+</p>
+
+<h2>Setting New Shortcuts</h2>
+
+<p>
+	Once an action of interest is located in the list, all it takes to set
+	a keybinding to it is selecting the action in the list, then pressing
+	the sequence of keys. The newly defined keybinding will immediately show up
+	in the <dfn>Shortcut</dfn> column.
+</p>
+
+<h2>Redefining Existing Shortcuts</h2>
+
+<p>
+	An existing shortcut to an action can easily be replaced with a different
+	one by selecting the action and pressing a new sequence of keys. The newly
+	defined keybinding will immediately show up in the <dfn>Shortcut</dfn>
+	column.
+</p>
+
+<h2>Handling Collisions</h2>
+
+<p>
+	Once a keybinding is assigned to an action, that keybinding is considered
+	taken. Attempting to assign that same keybinding to a different action will
+	result in a collision. Ardour will notify the user that the keybinding is
+	already taken (and by what action) and will ask to either reconsider or
+	force-set the keybinding to a new action.
+</p>

+
+<p>
+	Force-setting the keybinding of choice to a new action will remove
+	the keybinding from the action it was previously assigned to. A new
+	keybinding then can be assigned to that action.
+</p>
+
+<h2>Removing Existing Shortcuts</h2>
+
+<p>
+	In some cases it is desirable to remove a shortcuts entirely. Selecting an
+	action of interest, then pressing the
+	<kbd class="button">Remove shortcut</kbd> button at the bottom of the dialog
+	will do just that. The keybinding will immediately disappear from the
+	<dfn>Shortcut</dfn> column.
+</p>
+
+<h2>Reverting to Factory Settings</h2>
+
+<p>
+	If applied customizations to default keyboard shortcuts didn't work out,
+	it's possible to revert to "factory settings". Clicking
+	<kbd class="button">Reset Bindings to Defaults</kbd> will remove all
+	customizations and bring back default keybindings. Important: Ardour will not
+	ask for a confirmation!
