发布 信息：All the instructions have been written/posted by people who assume that I know stuff I don't know: For instance, they take for granted that I'll know what it means to "paste to toolbox" - well I didn't. What toolbox? Where? How paste? Several sessions (HOURS!) later, I somewhere or other (I was so lost that I can't recover the path) learned that I had to click on View, Toolbars, Booksmarks Toolbar, in order to "lift" the "goggles" to the "toolbox."
A long, long time ago, I took a math course from a full professor of mathematics, and was totally at sea - until he got sick, and his student/assistant took over the course. As a novice herself, she made things clear for me and I learned things.
