is it possible to automatically wrap text?

[olets]

Is there a way to have text (in W:, or %%begintext ... %%endtext, or something else) automatically wrap to multiple lines, following the same width as staffwidth?

I don't see what you want exactly.
%%begintext accepts an option which can be fill or justify in which case automatic wrap occurs.
There is no such option for W:.
Otherwise, %%staffwidth is an other way to set the left and right margins. So, if you want the width of the text lines to be the same as the staff width, better use %%leftmargin and %%rightmargin.

Aha, thanks I didn't know about those options. justify meets my needs, so now I'm using begintext + textoption 1
