How to enable selection of annotations for DoClickProc

Question

Hi,
I created a sample myDoClickProc() below as an action invoked by clicking text annotations.
The program works fine except that the clicked notes (text annotations) do not get selected.
Specifically, I cannot select multiple notes or copy them, though each of them can be deleted one by one.
Also the note size changes after execution of SDKInit(), perhaps scaling to 100% of PDF documents.
Please let me how to fix the problems.
Thank you.
static AVAnnotHandler originalHandler;
static ASAtom textAtom;
ACCB1 ASBool ACCB2 myDoClickProc(AVAnnotHandler annotHandler,
      PDAnnot annot, AVPageView pageView, AVDevCoord xHint,
      AVDevCoord yHint, AVFlagBits16 flag, AVTCount clickNo)
     ASBool ret = originalHandler->DoClick(annotHandler,annot,
         pageView,xHint,yHint,flag,clickNo);
     char buf[128];
     PDTextAnnotGetContents(annot, buf, 128);
     AVAlertNote (buf);
     return ret;
static ACCB1 ASAtom ACCB2 myAnnotGetType(AVAnnotHandler handler)
    return textAtom;
void SDKInit()
    textAtom = ASAtomFromString("Text");
    ASAtom name = ASAtomFromString("AVAnnotHandlerDoClickProc");
    originalHandler = AVAppGetAnnotHandlerByName(name);
    static AVAnnotHandlerRec newHandler;
    memcpy (&newHandler, originalHandler, sizeof(AVAnnotHandlerRec));
    newHandler.DoClick = ASCallbackCreateProto(AVAnnotHandlerDoClickProc,
        &myDoClickProc);
    newHandler.GetType = ASCallbackCreateProto(AVAnnotHandlerGetTypeProc,
        &myAnnotGetType);
    AVAppRegisterAnnotHandler(&newHandler);
    return;

Regarding the selection issue, I believe this could be solved by getting the original handler that is registered for Text annotation types, i.e. AVAppGetAnnotHandlerByName(textAnnot) in your SDKInit function.
Your approach has given me an idea to solve my own problem, here's hoping it works.
