^+c send {Alt}, and physical press the {Alt}, the behavior is different problem Topic is solved

When we click the Alt key in the Win program, such as Notepad, the menu can be activated. As shown:


But through the following code, we can not activate the menu: Why?

Code: Select all

^+c :: Send {Alt}

Tried:
① I Googled "ctrl send alt AutoHotkey", did not find the answer
② Try sendplay sendevent, not working too
③ Try #UseHook, not working
④ Try BlockInput to shield the impact of ctrl and shift, not work:

Code: Select all

^+c ::
BlockInput, On
Send {Ctrl Up}{Shift Up}{c Up}
Sleep 50
Send {Alt}
BlockInput, Off
Return

Although this problem has been solved in the following way:

Code: Select all

^+c :: Send {LAlt Down} ef {LAlt Up}

But what make me curious is the reason behind:

1. what cause the difference between Send {Alt} and pressing the Alt key using hand? Windows API RegisterHotkey() don't support it?
2. How does AutoHotkey activate the response of the menu bar in the GIF shows?

Thanks
