Marimba rolls?

Hi all,

How do I add roll markings to my marimba notation? They look like the double or triple lashes you see on the stems of violins when they’re repeating a rhythm.

It’s pretty straightforward.
Select the notes, press SHIFT-R (for Repeat) and the amount of slashes / you need.

That is exactly what I needed. Thank you.

Alternatively, just the number works too: SHIFT-R3Enter.
