Can't find macro for editing

Some time back I created a macro and added an icon to the toolbar. This is not a recorded one but one I started from scratch whereby naming it and everything. The macro works fine but I thought I'd tweak it a bit but now I can't find it in the macro manager. When I hover over the icon it reads as Module1.BlahBlah. Also can't find it in USer GMS folder or the Programs...GMS folder. You can't do a search in VBA Editor on "everything"? 

How can I find it to edit?
