I don't think this is needed, see my older post: http://groups.google.com/group/vim_use/msg/6cb2115dbbcfcd3b The following code makes use of it. Ok, the backdraw is: it will not work from a mapping or from @a (your new problem below), because getchar() -- when called from an expr-map (!) -- for some reason does not take the next char from available type ahead (as it should), but always asks the user for fresh input. omap w w<SID>copyreg " if the following is repeated with "." (e.g. "df_.") the expression " will not be evaluated again: ono <expr><script> f "f". <sid>Getchar(). "<SID>copyreg" ono <expr><script> F "F". <sid>Getchar(). "<SID>copyreg" " (should work as well:) " omap <expr> f "f". <sid>Getchar().

Looks like @ is "expr-mapped", ignoring the type ahead "a". > What I was hoping was there was some way from within an expression > function to see the full normal command.

At least this is what I've observed so far. -- Andy --~--~---------~--~----~------------~-------~--~----~ You received this message from the "vim_use" maillist.
