If you click Language -> Define your language... you can define code folding styles in the Folding in code 1 style boxes. You need to set a symbol which means "open the fold" (maybe "Topic") and a symbol which closes the fold (e.g. "Endtopic"). However, this will mean that you will need to add "Endtopic" to your files, so I'm not sure that this is an ideal solution – TheTurkey Jul 31 '13 at 11:04

You can define your own syntax highlighting and code folding rules by defining a 'User language'. Click Language -> Define your language... to open the User Defined Language dialog.

This dialog gives options for many levels of customisation. In your case, you could add the word 'Topic' to the 'Folding in code 1 style' open list.

Basically, View -> User-Defined Dialogue
Create New. I call it Txt, set the extension to .txt
In folder and default pane, set the open and close options.
I use {{ and }} respectively.

Then from the View menu, use the fold, collapse options.
