Collapse text instead of buttons

[Cle]

Hey there,

I have a vB 3.6.4 installed, and I'm looking for something that I still can't quite figure out yet. The default 3.6.4 version (as do the 3.0.X, 3.5.X and 3.6.X series if I remember correctly) has the collapse and expand buttons. However, the thing I want is that it does not appear as buttons, but as text such as "Collapse" (when the 'tbody' is collapsable) and "Expand" (when the 'tbody' is collapsed).

Is there any way to do this? It doesn't really matter if it involves file edits.

Thanks in advance!

Cle.
