Can I create a console application (think the Pine email reader or even
'edit' in DOS) where I can use my up/down/side arrows to move around the
app?
Yes.
>Any hints/pointers to get me started?
Marco
Use elements of Console for the cursor moving bit: CursorTop,
CursorLeft, KeyInfo, ConsoleKey, KeyAvailable and Read(). You may
also need System.Threadin g.Thread.Sleep( ) to wait for a key to be
pressed.
I don't know how much of a hint you want, but don't read any further
if you don't want to see a very simple demonstration.

static void Main() {
string twentyDots = new string('.', 20);
for (int i = 0; i < 10; ++i) {
Console.WriteLi ne(twentyDots);
} // end for
Console.WriteLi ne("Use arrow keys to move or X to exit.");
// Initial position of cursor
Console.CursorL eft = 9;
Console.CursorT op = 4;
// Loop to read keyboard
bool finished = false;
ConsoleKeyInfo keyInfo = new ConsoleKeyInfo( );
do {
// Wait until key is pressed.
while (Console.KeyAva ilable == false) {
Thread.Sleep(10 0);
} // end while
// 'true' stops key echo.
keyInfo = Console.ReadKey (true);
switch (keyInfo.Key) {
case ConsoleKey.Down Arrow:
++Console.Curso rTop;
break;
case ConsoleKey.Left Arrow:
--Console.CursorL eft;
break;
case ConsoleKey.Righ tArrow:
++Console.Curso rLeft;
break;
case ConsoleKey.UpAr row:
--Console.CursorT op;
break;
case ConsoleKey.X:
finished = true;
break;
default:
break;
} // end switch
} while (!finished);
} // end Main()
