如何使“输入”(或是上下文?)依赖于热字符串/热键?

:*:+h::
^h::    
    nr := ""  ; empty variable's content
    end_nr := ""
    Input, var, L2 ; Length limit=2
    ; Input, var, L2  V ; V: Visible
    If var is not integer
    {
        MsgBox, "%var%" is not integer
            return
    }
    first_nr := SubStr(var, 1, 1)  
    second_nr := SubStr(var, 0)
    if (first_nr >= second_nr)
    {
        MsgBox, "%first_nr%" is greater or equal "%second_nr%"
            return
    }
    Loop
    {
        nr++    ; increase the number in the variable "nr" by 1 in each iteration
        if (nr < first_nr)
            continue    
        If (nr = second_nr)
            break   
        end_nr .= nr . "," ; concatenate the outputs by adding a comma to each one
    }
    If (first_nr = 0)
        MsgBox, "0,%end_nr%%second_nr%"
    else
    MsgBox, "%end_nr%%second_nr%"
return
