Note expression problem with the draw pencil

hi sorry for my bad english but i try to explain.
today i try to use the note expression method…i really like that but when i try to modify a note…
i take the pencil but i can’t draw a multipoint sine…i can write only a line-.-
i cant use the parabol or sinus…i can’t create other point in the note…why?
i see some tutorial and they can draw…

Sounds like you have “one-shot” mode turned on. (see manual p. 574)

theres a small arrow under the line shortcut…click on and u get many option like parabol …hand free …

thanks mans! is one shot active!
thanks a lot!
