以下是一个可以实现按下Q键模拟鼠标右键的易语言代码示例，你可以在此基础上进行修改来实现长按和松开的操作：
```
' 引用 Windows API 函数库
Private Declare Function mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long) As Long
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer
Const MOUSEEVENTF_RIGHTDOWN = &H8
Const MOUSEEVENTF_RIGHTUP = &H10
Const VK_Q = &H51
' 定义Q键状态的变量
Dim qKeyDown As Boolean
While True
' 获取Q键状态
If GetAsyncKeyState(VK_Q) 0 Then
' 如果Q键处于按下状态
If Not qKeyDown Then
' 模拟鼠标右键按下
mouse_event MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0
' 设置Q键状态
qKeyDown = True
End If
Else
' 如果Q键处于松开状态
If qKeyDown Then
' 模拟鼠标右键松开
mouse_event MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0
' 设置Q键状态
qKeyDown = False
End If
End If
