Hi, as i am learning myself the shortcut, before asking the students to do so 
i have some trouble with the keys
an exemple: comment/uncomment block/line > meta (ALT)-/
we cannot do this on our keyboards 
especially this last shortcut is very useful during performance… so what can we do to fix this ? is there a way to modify it ? i mean a different key ? or in the “right-click” options ? somewhere easy to access by menu or key
thanks for your help
