The keystrokes that work are...

For length of note (the horizontal line)

Place the mouse cursor in the center of the note-head, hold the right button down and drag right (to the length you require).



For the velocity of the note (the vertical line)

Again place the mouse cursor in the center of the note-head, hold the right button down and drag up (to the length you require).


If you go to 1:13 in the below video clip, it's explained how staff roll mode works.
