I would like to create a Subtitle environment that will be available in the Environments dropdown while using memoir. I've tried editing stdtitle.inc, memoir.layout, and creating a subtitle.module
This is what I am trying to define... same as "title" but one size down.
Style Subtitle Margin Static LatexType Command Category FrontMatter InTitle 1 LatexName subtitle ParSkip 0.4 ItemSep 0 TopSep 0 BottomSep 1 ParSep 1 Align Center LabelType No_Label Font Size Larger EndFont End
Editing stdtitle.inc or memoir.layout, I do see "subtitle" in my drop menu, but on export I get the error below:
The control sequence at the end of the top line of your error message was never \def'ed.
In the custom module, I get an error saying the module "subtitle" requires packages, and is missing the prerequisite "subtitle"
How do I define subtitle so 1) I can access it in the dropdown, 2) it's understood by Lyx, and 3) exports correctly?
