Zotero preferences
I used zotero many years ago and have just come back to it and I know I must be doing something stupid because I cannot find any toolbar or pane (not sure of terminology) to change my preferences. Everything thing I've looked at assumes you have a pane to click on and edit but there is nothing....

Thank you, it was a rather frustrating hour.
