On the Outline View, it provides commands for editing the document:
- “Undo” and “Redo”
to reverse and restore changes in the
document.
- “Delete”
removes the selection from the
document.
- The “Insert Container/Variant/Event/Additions" operations are
only available when valid in the selected area (e.g. events can
only be inserted into a layer - see MEI schema) and offer quick
access to often used elements.

- The Measure elements can get relabeled via right-click them and
selecting "Relabel Measures"
.
- The “Clone”
command duplicates the selected
element with default initial values.
- To save your changes, click “Save”
on the bottom of the context menu. This button is
disabled when no saves have been made since the last save.
