Instead of "current" wouldn't it just be getCaretPostion?
Why would you abbreviate Position to Pos, or drop the word Position
altogether?

Keeping AbiCollab in mind would you need to have a way to get the postion
of Caret N, N+1, ... (perhaps that would simply be an additional argument
to the getCaret API).

Presumably this is needed so that after something like a find and replace
you can just put the caret back to where it was before the a script was
exectuted? I guess what Daniel is trying to do will matter in the short
term but that you'd want the more generic functions in the long term in
any case.
