No, you cannot do that by defining a macro-command, you need to write a
new command in Java or in one of the supported scripting language
(BeanShell recommended).
The main reason is that unlike selectNode, the selectNodeAt command has
not been designed as a reusable tool. For example, if "selectNodeAt
extend" cannot do its job, it will do nothing at all instead of
reporting the fact that it cannot do it.
Writing a command will be described in the Developer's Guide (next
release, expected at the end of this month). (For example, selectNodeAt
is 100 lines of Java.)
PS: note that even if you write a new command you cannot bind it to
Shift-Ctrl-Click because, for now, it is not allowed to override
standard bindings, just to augment them.
