i tried that, but the keyPress does not tell which key was pressed....
For instance, there is a keyUp() and keyDown() but no for left and right key presses...

[Filip Hracek]

try using e.charCode, which should hold the pressed key's charcode

element.on.keyPress.add((e) {

    if (e.charCode == 13) // Enter

        print("Enter pressed.");

});

will try that but the solution that worked for me was:
document.on.keyDown.add((Event e){
  KeyboardEvent ke=e;
  //print(ke.keyIdentifier);
  if (ke.keyIdentifier=="U+0061" ||ke.keyIdentifier=="U+0041")
{}
}
 
});
Hope this helps some1 else :)

window.on.keyUp.add( (KeyboardEvent e) {
  
   if (e.keyCode == 27) // 27 for ESC, 13 for ENTER, etc..
   {
      // code
   }
              
});
