The list editor is a fallback editor for when a more specialised editor is not available.
Currently it displays either a list of Parts, or the events contained in a Part. If the link button is enabled for the window, making a selection will affect the selection in the other windows.
Some Part properties can be edited by selecting the relevant row, then clicking on the Start, Length, or Name columns.
To delete a Part, use the DELETE key, or use the context menu.
The window can be docked to another window by dragging from the empty space in the toolbar.
