<p>
The <kbd class="window">Keyboard Shortcuts</kbd> dialog allows easily
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!
