Autohotkey. How to make work both `a hotkey` and `a hotkey+key`? - autohotkey

Question

I want to have two hotkeys in my script. Namely LWin Up and LWin+LAlt Up. I've tried to do it like that:
LAlt & LWin Up:: ;I've also tried commenting out the first
LWin & LAlt Up:: ;or the second line
LWin Up::
msgbox, % A_ThisHotkey
return
But the output depends on the order in which keys were pressed and released. The time between releasing the first and the second key also affects the result. Sometimes I get two MessageBoxes, sometimes just one and sometimes even none at all (the first line is commented out, press alt, press win, release win, release alt). How do I make it work? To be clear: I want to get only one MessageBox.
In the answer it would be great to see a script that provides full information about the hotkey pressed and the order in which the keys it consist of were pressed and released. *Only one hotkey should be triggered after releasing a hotkey+key combo.

Answer 1

You can not put them altogether.
you should use something like this:
altPressed := false
LAlt & LWin Up::
msgbox, % A_ThisHotkey
return
LWin & LAlt Up::
msgbox, % A_ThisHotkey
altPressed := true
return
LWin Up::
if !altPressed {
msgbox, % A_ThisHotkey
}
altPressed := false
return
If what you want to do instead of msgbox is too spreaded in my code you can use the below one:
SetTimer, toDo, 10
toDo:
if doWhatEver {
;; HERE DESCRIBE WHAT TO DO
doWhatEver := false
}
return
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
altPressed := false
doWhatEver := false
LAlt & LWin Up::
doWhatEver := true
return
LWin & LAlt Up::
doWhatEver := true
altPressed := true
return
LWin Up::
if !altPressed {
doWhatEver := true
}
altPressed := false
return

TechJS's answer wasn't working exactly as I wish so here is my script. It detects the order in which the keys were pressed and released, and doesn't depend on time between keys pressed/released.
global firstPressed := ""
LAlt::
altDown := true
if (winDown)
return
firstPressed := "!"
return
LWin::
winDown := true
if (altDown)
return
firstPressed := "#"
return
LAlt Up::
altDown := false
if (!winDown) {
if (comboJustUp) {
comboJustUp := false
return
}
msgbox !
}
if (winDown) {
comboJustUp := true
if (firstPressed = "#")
msgbox #!!.
if (firstPressed = "!")
msgbox !#!.
}
return
LWin Up::
winDown := false
if (!altDown) {
if (comboJustUp) {
comboJustUp := false
return
}
msgbox #
}
if (altDown) {
comboJustUp := true
if (firstPressed = "!") ; \here is one bug though. If you switch theese
msgbox !##. ; /two lines
if (firstPressed = "#") ; \with theese
msgbox #!#. ; /two. It won't work correctly for some reason
}
return
