autoit3 - trigger context menu to open on button click/press - autoit

Question

I am working on a project, in which I decided I should have history of previously searched stuff (since it's an app with which you can search stuff), so I have been thinking that I could just create the context menu or regular menu, that I could somehow force to activate on a button click or by using accelerators.
Now, I haven't been able to figure out how to make that work.
First I tried the GuiCtrlSetState() function, which didn't seem to work (I tried show and focus), then I tried accelerators and they didn't do anything.
So I'm wondering is there any way I can make the context menu or regular menu pop up on button press/click or key press (with accelerators)?
So what I'm basically trying to do is some sort of a pop-up, you click on a button or press a key to trigger the context menu or regular menu to open.
I know I could be old school and use a new GUI or just a combo box for the history or anything but I kinda want this, if there's any way to do so.
Any help, or an alternative way of doing the same thing appreciated.
Here's the testing code in which I was trying to make the test button trigger and activate the context menu, and I have tried the same with the regular
menu: 
#NoTrayIcon
#include <GUIConstantsEx.au3>
GUICreate("test123")
$but = guictrlcreatebutton("test", -1, -1, -1)
$xt = GUICtrlCreateContextMenu("test context menu")
GUICtrlCreateMenuItem("test1", $xt)
GUICtrlCreateMenuItem("test2", $xt)
GUISetState(#SW_MAXIMIZE)
While 1
$msg = GUIGetMsg()
If $msg = $but Then
GUICtrlSetState($xt, $GUI_FOCUS)
EndIf
Sleep(5)
WEnd

If you check the help file under GUICtrlCreateContextMenu:
; right click on gui to bring up context Menu.
; right click on the "ok" button to bring up a controll specific context menu.
#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>
