+### Shortcuts editor
+
+This category exposes all the shortcuts, sorted by category.
+
+![](img/options/shortcuts.png)
+
+Each item is editable.
+
+- <img src="{%include icurl%}other/clean.png" class="tlbric"/>: Deletes the current assignation.
+- <img src="{%include icurl%}other/keyboard_pencil.png" class="tlbric"/>: Displays the editor. The shortcut can also be selected in the combo menu.
+
+After an assignation attempt and if the selected combination is already used the new shortcut is not validated and a warning is displayed.
