I've learned here that there are two ways to modify an \item
:
- [@123]
will set the counter of enumerations (or "ordered lists") to 123.- [$Rightarrow$] :: bla
will generate a "description".
Both do not really yield the flexibility that I was hoping for in my question, but it seems that this is as far as one can get.
EDIT:
I've stumbled over a not so obvious way to gain full flexiblity:
- @@latex:[bla]@@[$\Rightarrow$]@@
will turn the item bullet into "bla"be exported as\item[$\Rightarrow$]
Notice that @@beamer:[bla]@@[$\Rightarrow$]@@
does not effect this.
