How to trigger an action if there's only one key being pressed? - scripting

Question

Here's my current script:
Shift::Send ^{Space}
It doesn't only trigger ^{Space} on pressing Shift alone, it also triggers on Alt+Shift (just these two keys) and Ctrl+Shift (just these two keys) if Shift is the last released, is there a way to trigger ^{Space} if Shift is the only key being pressed?
AutoHotkey Version: 1.1.33.09.

Answer 1

I have your answer and to think I only learned this today.
~Shift::return
#If, A_PriorHotkey = "~Shift"
Shift Up::
SendEvent, ^{space}
#If
return
Worked for me. The ' ~ ' symbol will let you still type capitals although it will still send the ^{space} still. Either delete it (it still works) and/or You will have to make this script Context-sensitive right?
P.s.
I learned it from another code and just adapted it to my and your needs. I needed almost the same thing as you today :-)
Here is the old code I found which I adapted
^k::return
#If, A_PriorHotkey = "^k"
^a::ToolTip, % A_ThisHotkey " pressed with ^k"
^b::ToolTip, % A_ThisHotkey " pressed with ^k"
^c::ToolTip, % A_ThisHotkey " pressed with ^k"
^d::ToolTip, % A_ThisHotkey " pressed with ^k"
^k up::SendInput, ^k
#If

Answer 2

This works for me.
~Shift::return
#If, A_PriorHotkey = "~Shift"
Shift Up::SendEvent, foo
!*c::SendEvent, foo
#If
return

Answer 3

try this:
Shift::
SendEvent, foo
return
Ctrl & Shift::return
Alt & Shift::return
This doesn't work with Numpad keys though for some reason. And again, this script will have to be Context-sensitive.

Answer 4

Here's my working script:
~*Alt::
~*Ctrl::
~*Shift::return
Shift::SendEvent ^{Space}

Answer 5

Yup Simple, Put the '~ Tilda' key next to it.
~Shift::
SendEvent, ^{Space}
return
