REALbasic Tip: Is the user is pressing a command-arrow key combination?

[Geoff Perlman <geoff at realsoftware dot com>]

The example below demonstrates how to determine if the user is pressing
command and an arrow key even if no windows are open.

Put this code in the EnableMenuItems event of the Application class or a
window to see it work.

  If Keyboard.AsyncKeyDown(123) then
    MsgBox "left"
  end if
  If Keyboard.AsyncKeyDown(124) then
    MsgBox "right"
  end if
  If Keyboard.AsyncKeyDown(125) then
    MsgBox "down"
  end if
  If Keyboard.AsyncKeyDown(126) then
    MsgBox "up"
  end if
