程序代码：

If KeyCode = 37 Then '键盘按键左边←
Call Image1_Click
ElseIf KeyCode = 39 Then '键盘按键右边→
Call Image2_Click
End If
End Sub
Private Sub Form_Load() '定义文字数组，初始化timer控件、索引值i
Timer1.Enabled = fasle
Timer1.Interval = 100
myarray(0) = "大": myarray(1) = "小": myarray(2) = "多": myarray(3) = "少"

End Sub
Private Sub Image1_Click() '移动到上一个字
If i > 0 Then

End If

End Sub

End Sub
'Timer控件实现文字移动效果，如果移动到中间位置就停止。
Private Sub Timer1_Timer()
If Label1.Left < 5000 Then
Label1.Left = Label1.Left + 200

学习总结：
1、harrow.cur为windowsXP的系统图标，windows7中没有，要在win7中运行则需要修改成其他图标，否则报错。
2、方向键的键盘码keycode如下：
keycode 37 = Left ←
keycode 38 = Up ↑
keycode 39 = Right →
keycode 40 = Down ↓
3、如果使用if...else语句，else遵循就近原则。
