Example not working for me. How to sense what template I am using?

I am trying to use…

{{#checkIf template '==' "MYTEMPLATE"}}

…but am not sure what value to use.

Cuurently, I have one head partial per post index, author, post, tag as index-head.hbs, author-head.hbs, and so on.

I am trying to create a single head.hbs where I can sense which template I am using and changing the contents within a div tag.

I have tried post, post-head, post.hbs, post-head.hbs as examples.

None of these seem to work.

I also see…

{{template}}

and within a…

{{#post}} {{/post}

… returns nothing. I used this to try and figure out what value I should use in the checkIf example.

No such luck-

Are there any clues as to what should replace MYTEMPLATE to sense if the template is index, post, author, or tag?

Cheers!!
