Where is “Generate Sequence Diagram” in the V. 8

[arboboo]

In the version 7.5,  I can get “Generate Sequence Diagram”  as follows:
1.      Import the source directory first.
2.      Right click on a method in the Project Browser window.  And then In the right click menu, I can find that item of “Generate Sequence Diagram Ctrl + Shift + F6”.

 But in the version 8,  I cannot find it in the right click menu. Where is it?

Thanks.
