I'll illustrate with an example of case fallthrough
from a hypothetical *craft clone:

switch(kee)
{
  case 'a':
  case 'A':
    clickMode = CLICKMODE_ATTACK; // attack an enemy or structure
    break;
  case 'b':
  case 'B':
    curMenu = BUILD_MENU; // basic structures
    break;
  case 'v':
  case 'V':
    curMenu = BUILD2_MENU; // advanced structures
    break;
     //   ///       //
    ////  //  //// ////
   // // // // // // //
  ////  //  //// // //
  default:
    PlaySound("DING.WAV"); // invalid
    break;
}
