[Pharo-users] Finding references to traits

[btc]

If I come in cold to a system and see some class using trait, and then I 
want to find all classes that use that trait. I have tried a few ways 
but failed to work it out. The most obvious action "Extended search > 
references of it" doesn't show them, and neither does any other action I 
try. How is this done?
