I don't think that this could be possible, because some of the predefined
Variables have some
action behind them, like searching for an array, so I think they are defined
somewhere in the Source Code.

I think you didn't get that right.
They wrote: "evaluate to the name of the variable itself" and that's exactly
what is meant.
1. Try defining a template in "preferences->java->editor->templates" with
name "TempTest"
2. write somewhere in this Template: ${MyTestVariable}
3. open a Java-Editor
4. Type in: "TempTest" and press Ctrl-Space.
In the Source-Code now ${MyTestVariable} is replaces with "MyTestVariable".
That's neither nice nor smothe, but it's exactly
what the help is saying.

Now you are asking: Why then define an Template Variable?
Because when the same Variable appears more than once and you overwrite the
Variable right after pressing Ctrl-Space,
all occurences are replaced at the same time.

For more infos, look into the Eclipse-Help:
Getting Started->Basic tutorial->Editing Java Elements->Using source code
templates
