[setting vertical space between lines[_2_]]

Hello
I have word 2002.

Would there be any way to make the text of the entries appearing in a table
of figures(Insert menu-Reference-Index and tables) shorter than the actual
text appearing along the document for each figure?

For example, let's say I have a figure under which this message can be read:
"Figure 1: this figure represents the speed of the cat vs the speed of the
lion in the middle of the forest"

But let's say I do not want that this long message appears in the table of
figures. Nonetheless, it is appearing like that so far. Is there any way to
change a little bit the entry in the table of figures for this message in
order to make it shorter?
For example, the message in the table of figures would just be:
"speed: cat vs lion"

The thing is that I knew how to do this with word indexes because with the
XE label I can set the text I want for the corresponding index entry. But for
this case of tables of figures, I still do not know how to do that. ¿Is not
there a XE entry or something like that for the tables of figures?

Thanks in advance
