AutoHotKey: remapping Alt+Shift+<plus> to \

I would like to have a autohotkey remap for Alt + Shift + nonnumpad_plus_sign (equivalent to Alt + ? in my keyboard) and have that send a backslash '\'

I've tried stuff like:

!+NumpadAdd::\ 

(which works, but I want to use the non-numpad + sign of the keyboard).

Also this works:

!+::\

(Alt + nonnumpad_plus_sign = \, but how can I have shift and + in the same line?)

Any ideas?

Thanks!

Edit: the solution for my case following the steps in the answer below is

!+SC00C::Send, / 

but also

!++::Send, / 

works as well, perhaps more elegant solution (the first + represents Shift, the second the + sign)

Solution 1:

To click the + key on my keyboard I need to type Shift+=.

Therefore Alt+Shift++ is remapped as follows:

!+=:: Send, \

If your keyboard is different, it might require a different combination.

For example, you may be able to define the key using its scan-code. To find it out:

• Create a .ahk script containing this one line:

  #InstallKeybdHook
  

• Run the script

• Right-click its traybar icon (green H) and choose Open
• Click the menu View > Key history and script info
• Press the +
• Press F5
• Note the three-digits code that is next to the key

Assuming that the scan-code was 123, the following script might work:

!+SC123:: Send, \
