Move a Hit

Hi - Can someone tell me how to move a hit?
Right now, it's in the middle of the staff and I need it at the top of the staff (bar 28)

thanks

Note, that the previous steps that I used no longer work - maybe because of MuseScore updates:

Select the slash(es) (Command + Select) you want to move.
The Inspector window opens in the form of a vertical bar to your right. 
OR
Select fn + F8
Adjust the Y value under the Chord group (even though it’s not a chord that you are adjusting). 
Example: My slash was over the F note at the top of staff. I wanted the slash to be floating over the staff so I adjusted the value to -3.50sp
