Answer 1

You can call key_name( c ) to turn the key generated from getch() into something that shows you the state of the ctrl-modifier.

For example this code shows "^R" if you press ctrl-r:

while( true )
{
   char c = getch();
   if ( ERR == c )
      break;

   const char *name = key_name( c );

   move( 2, 2 );
   clear();
   printw( "You entered: %s             ", name );
   refresh();

}
