I tried all 10 input forms in the last 2 lines of Basic Bath palette.
I filled them with undefined symbols like a,b,c and pressed enter.
My preliminary conclusions:

1-none of the forms (except the 2 mentiond by David)  have a
predefined meaning
2- the ones mentioned by David generate a syntax error.
Mathematica apparently expects something more or something different
than undefined  a,b symbols.

These 2 input forms could be used in Chemistry to indicate atomic
properties or perhaps in mathematical physics to indicate some special
function.

They might  have a preassigned meaning, since Mathematica expects a
more complex input syntax.
