[OS X TeX] Macro sheets in TeXShop?

[Alain Schremmer]

I write essentially three different kinds of LaTeX---for text. for  
ancillaries, and for the code to manage the ancillaries---and I have  
different stylesheets for each kind.

I was wondering if there could similarly, somehow, be different  
TeXShop macrosheets as I end up never using more than about one third  
of my (many) macros---which third depending on the kind of LaTeX I am  
writing.

Not too hopeful regards (inasmuch as I am running TeXShop 2.47 under  
10.5.8 on a PPC.)
