Hello,
I noticed that when I transform a selection from normal note to slashes rhythm,
using right-click / Voices / Rhythmic slashes / slashes with stems,
the entire staff gets transformed into slashes.
Also, is it possible to use the Pop over to change a selection to slashes with stems?
Best regards,
That function redefines the selected voice as a different type of voice.
If you want to change the selection, you need to use the Change Voice options, slightly further down the same menu.
I don’t believe it’s possible to achieve this via the popovers.
Thank you pianoleo 
I found the Change voice option and it works as only the selection gets slashes.
But I lose the playback though
Playback Options > Repeats > Rhythm Slashes > Play Slash Voices.
I believe it’s unticked by default.
Woah 
You are the best 
Thank you for your help
