AutiHotKey Some key combinations are not intercepted (ex 3,4,5)

I want to remap the keyboard in the following mode:

2::ctrl
3::shift
4::alt
5::tab

My problem is that pressing at the same time 3,4,5 (equivalent to pressing alt shift tab) does not work. After investigating a little I have found that ahk can not catch some keys when being pressed together (2,3,e OR 3,4,5). Here is my code through which I have found out this

2::
    tooltip 2
    sleep 500
    tooltip
return
3::
    tooltip 3
    sleep 500
    tooltip
return
4::
    tooltip 4
    sleep 500
    tooltip
return
5::
    tooltip 5
    sleep 500
    tooltip
return
e::
    tooltip e
    sleep 500
    tooltip
return

Anyone knows of a workaround to catch multiple key presses (like 2,3,e OR 3,4,5) ?

Thanks !

Your first code (the remapping) works faultlessly on my system. Something else is wrong in your script or your system. Try it first of all as a stand-alone script. – user3419297
I have tried it as a stand alone script and same result, you mean that while pressing 3,4,5 the behaviour is the same as alt shit tab (not alt tab?). If so, what windows and ahk version you using ? – Ciprian Dragoe
I have tested it on Win7 and Win10 both 64bit. 3-4-5 is the same as alt-shift-tab. Maybe your keyboard driver needs to be updated. – user3419297
strange I have also tested on multiple PCs and the keyboard drivers are up to date, if you have time, could you please also test to see if 2+3+e works (ctrl+shift+e as a hotkey) – Ciprian Dragoe
After some experimenting with 3 old keyboards (not MS or Logitech), I found out that your code only works with my standard keyboard MS Digital Media Keyboard 3000. – user3419297

This is probably a limitation of your keyboard - some keyboards can't handle particular combinations of three keys, which is known as "key jamming." See the "Key jamming and ghosting" section in the Rollover (key) page on Wikipedia.
