By default, ELAN automatically displays all available tiers, but each tier can be switched on or off manually, allowing you to focus only on the tiers of interest for the task at hand.
To switch tiers on/off, do the following:
In the Timeline Viewer, right-click in the tier name panel.
In the pull-down menu select the submenu
and (un)check the tiernameSwitching off a tier can be done directly by right clicking on its name and selecting
from the pull down menu. Alternatively you can open a window containing all tier names by selecting in the popup menu.
If you switch a tier on, it will be put on the place
where you clicked.
