Email templates-from Setup or email screen?

Email templates-from Setup or email screen?

Hello,

I'm confused on the email templates.  I originally set up several by going through Setup - Email Templates.  They would be available to select from the Compose email screen - can't remember exactly where.  Now they are not there, but they are still in the email templates.  I can't figure out how to use the templates now.

On the other hand, I typed a new one from the email program and clicked Save Template.  I can use those, but how do I access the ones which were named and saved through the setup menu?  Are these two separate template programs?  

Thanks for your help,
Laurie
