I’m not sure what you mean by that. \afterGrace takes two arguments, both of which are a single music expression each. {} or <<>> are used to combine multiple things into a single music expression (sequential or simultaneous).
If you want to use \afterGrace but are unsure of the order or type of arguments, the easiest way to find out is the Command Index, Appendix D to the Notation Reference Manual. It will allow you to quickly get both to the verbose explanation in the NR, and to the concise entry in the list of available music functions. General syntax questions are probably addressed better by the Learning Manual, as long as it’s pure LilyPond syntax (without Scheme expressions).
