Opentype/special characters

[D L Reynolds]

Please forgive me if this has been covered a million times...

I'm using FrameMaker 7.1 on Windows XP with Opentype fonts, but I'm 
primarily a Macintosh person. It's my understanding that Opentype 
expands the Windows character set, but I can't find anything like a 
Glyphs palette or a keyboard command that will enable me to enter a 
simple "less than or equal" sign without having to resort to the 
Symbol font.

Is there a way to coax special characters out of Opentype fonts on 
FrameMaker Win?

Many thanks.
