Hi Lawrence,
The manual doesn't mention the toolbar because I added that after
Guide 7 started shipping. However, if you take a look at "Settings...
Toolbar", you should have no problem in turning buttons on or off and
in switching from the (default) small buttons to the larger buttons.
To get toolbar tips, you'll need to use the current software;
the tips will then automagically appear on the application title bar,
both for toolbar buttons and for legend items. That is, move the
cursor over the time shown in the legend, and the application title
bar will have a blurb telling you what clicking in that area will do.
For gory details, including how you can reset the actions that
result from clicking in the legend area:
