Auto Hot Key: 1 Click Heroic Leap / Blizzard Macro

Hey Guys,
I hope this is the right place to post this. I was trying to make a script which will automatically cast and execute Heroic Leap for my warrior or Blizzard for my mage. This can be especially usefull in Pvp to save some time. My Heroic Leap and Blizzard are currently bound to Shift and Mouse Button 4, so I want the Script to automatically Left click for me as soon as I press Shift and Mouse Button 4. I found a script online and tried to get it to work, but it doesnt.
The Left key is triggered, but whenever I activate the script, the Wow ingame hotkey, which casts Heroic Leap / Blizzard is disabled. So Heroic Leap is not casted for some reason... Could someone please help me with that? I have been trying for over an hour now and I am getting very frustrated..

ins::suspend
XButton1 & Shift::
Sleep 5
Send, {XButton1 & Shift::}
Sleep 20,
Send, {LButton}
return

Would be really happy about some help!

Edit: If you dont understand what I mean by 1 Click Macro, that is what it should do in the end:

@Noe,

Look "here" for information on "Event on Keypress" look for my post. Use the basic LegacySpellManager to cast the Click location.

Is there anyone who has come up with an answer because I looked for this everywhere and it seems to be impossible as well as against ToS for Blizz. So figuring those two are true I'd come to my bot website and ask if anyone can help me out. lol
