can't onKeyPress event

[hyeon]

function onKeyPressed(code,ctrl,shift){
if (code==67&&ctrl){ // ctrl + c : copy
if (!mygrid._selectionArea) return alert(“You need to select a block area in grid first”);
mygrid.setCSVDelimiter("\t");
mygrid.copyBlockToClipboard();
}
if (code==86&&ctrl) { // ctrl + v : past
mygrid.setCSVDelimiter("\t");
mygrid.pasteBlockFromClipboard();
}
if (code==67&&shift){ //I make
mygrid.setCSVDelimiter("\t");
mygrid.copyBlockToClipboard();
}
return true;
}

[ctrl + c] & [ctrl + v] was good working But…
I want another keypress… then I make [shift + c].
but It’s not working…

All other Keys not working too… Why??

Unfortunately the clipboard operations will work only with the default clipboard keyboard shortcuts.
