The Edit tools dialog only allows to add 6 different tools. However,
in the tools demo, there are many other tools which are not in the
list when you click on Add. For example, how do you add
ChartToolSet1ZoomIn or ChartToolSet1PanHor?

By pressing "Add" button and selecting "Zoom click" and "Panning drag"
correspondingly from the drop-down menu.
Or maybe I did not quite understand your question?

That's what I did and it simply added ChartToolSet1ZoomClickTool1 and
ChartToolSet1PanDragTool1. It didn't add ChartToolSet1ZoomIn or
ChartToolSet1PanHor. I think there is something I don't get.

You can change the component name by editing "Name" property in the
object inspector.

OK! I thought the names were predefined. So in the tools demo, the
zoom click tool was added several times but under different names? I
guess the idea is to bind to them different properties or events. I
think I am starting to get it, thanks a lot.

Yes, this is the general principle of Lazarus/Delphi form editor.
You add components, which by default get generic names like "Button1",
"Button2" etc.
However, it is a good style to give a meaningful names to the
components
in non-trivial applications.

If you go to editing name property, ou should be able to rename the
component...  That usually works for me.

Think smeone else mentioned this as well..  MMMmm
