I'd suggest to use the TextStyle indirection, so you don't have to guess wether the font is a Strike font or a TTFont or whatever:

	'foo' asText
		addAttribute: (TextFontReference toFont: ((TextStyle named: 'Darkmap DejaVu Sans') fontOfSize: 20));
		openAsMorph


If you are just after changing the font used in a TextMorph (not the text itself), I'd use

	'foo' asTextMorph 
		beAllFont: ((TextStyle named: 'Darkmap DejaVu Sans') fontOfSize: 20); 
		openInHand


That way, the name string can be easily exchanged, such  as 'BitstreamVeraSans', or anything imported with the FontImporterTool

I think the "TextFontReference toFont:" and explicit "addAttribute:" are a bit involved; maybe something akin to Text>>#makeBoldFrom:to:/Text>>#allBold would be nice.


Best regards
