or press Ctrl+H. The slur appears:
As you can see the slur has 3 handles. By left clicking and dragging these handles you can determine the exact slur shape:
Although the slur handles appear to be free replaceable, they are always assigned to a symbol. The symbol is shown by a thin light blue line:
This has consequences:
NtEd tries to keep the position of the slur handle relative to the symbol it is assigned to;
NtEd removes the slur if the symbol it is assigned to is removed;
To change a slur's shape make sure NtEd is in edit mode (see The 3 modes). Select the start or end of a slur with left mouse button. The 3 handles appear again:
Thus, you can change the slur's shape again by dragging the 3 handles.
To delete a slur make sure NtEd is in edit mode (see The 3 modes). Again: You can achieve this mode temporarily by pressing the Ctrl key. Left click the start or and of a slur. The selected handle appears in red color. Press the backspace key and the slur will be deleted.
