I wish that the list of named Styles appeared somewhere on some submenu in the menu system of Scrivener (tucked away as obscurely as you like) --not just on the pop-up menu on the Ruler.
The benefit should be this: Then, when I tell OS X to associate key commands for my custom Styles (as I can do through System Preferences), these key commands would still work even when the Ruler was not visible and also when I was working in full screen.
Best,
Greg
P.S. I am not interested in Styles here for any “page layout” purposes, but purely as an aid to the writing process. My current use for custom styles is to achieve a kind of visual outlining within a single Scrivener document (a function in Word I find enormously useful). It is just several defined styles with different levels of paragraph indenting. Works wonderfully in Scrivener: I get the levels of indent as a visual outlining aid and Scriv defaults to just what I want: simple doc printing shows me my levels, but exporting by default does not–so it remains an internal organizational device for writing, safely isolated from the page layout process. I would just love to be able to use this within-document outlining strategy in full screen. Hence this note.
