If I create new notes there always open, I can sustain them. But I'm not sure how to change there notes? to 5 or 14 or 17 or bend them or hammer on them ETC. I usually do that in Guitar pro so no problem. But I missed a few notes and need to fix it. 

 

 

For the fret number either using CTRL+ number for 1 to 10 and CTRL+Fx for 11 to 19 (can also use CTRL+mousewheel)

 

Or use the edit note panel by pressing "n" when you have a note selected, you can edit the fret number, the mute and many other little parameter in there.

 

For bend i strongly suggest to use tech note as they offer more control over the bend but the bend status by using CTRL+B works fine enough for a simple bend.

 

There's a lot of hotkey available so play a bit around in the menu and with your keyboard and you'll find an impressive amount of possibilities opened to you.

 

PS : also use the help menu to get to some basic tutorial and an hotkey list.

thanks man :)
