secure actionbutton macrotext and modifiers

[saxitoxin]

How do I add a modifier to a secure actionbutton macrotext?

what I want to do is make my mount macro into a addon, but I cant get the [mod] command to read

mount macro code

#showtooltip
/cancelform
/leavevehicle
/stopcasting
/cast [mod:shift] Traveler's Tundra Mammoth ; [mod:ctrl] Azure Water Strider ; [mod:alt] Obsidian Nightwing
/run if SecureCmdOptionParse"[nomod]"then C_MountJournal.Summon(0)end

my testcode to see that [mod] is not working

yes, I know that I should post the entire code, but it is such a horrible mess right now so I made this one instead to describe my problem

local HSframe = CreateFrame("BUTTON","homeButton", UIParent, "SecureActionButtonTemplate")
HSframe:SetPoint("CENTER")
HSframe:SetSize(42, 16)
HSframe:EnableMouse(true)
HSframe:RegisterForClicks("AnyUp")
HSframe:SetAttribute("type1", "macro")
HSframe:SetAttribute("macrotext", "/use [mod] item:128353; item:6948")
 
HSframe.icon = HSframe:CreateTexture(nil,"OVERLAY",nil,7)
HSframe.icon:SetSize(16, 16)
HSframe.icon:SetPoint("LEFT")
HSframe.icon:SetTexture(1,1,0)
 
HSframe.text = HSframe:CreateFontString(nil, "OVERLAY")
HSframe.text:SetFont(STANDARD_TEXT_FONT, 16, "THINOUTLINE")
HSframe.text:SetPoint("RIGHT")
HSframe.text:SetText("HS")

It doesn't work because SetAttribute("type1", "macro") explicitly means it's only a "macro" for unmodified left-clicks, you probably just want "type" in there (or "*type1" for any left-clicks).

[Phanx]

Just use "type" without any numbers, asterisks, or modifiers.

local button = CreateFrame("Button", "MyAwesomeMountButton", nil, "SecureActionButtonTemplate")
button:SetAttribute("type", "macro")

button:SetAttribute("macrotext", [[
     /cancelform
     /leavevehicle
     /stopcasting
     /cast [mod:shift] Traveler's Tundra Mammoth ; [mod:ctrl] Azure Water Strider ; [mod:alt] Obsidian Nightwing
     /stopmacro [mod]
     /run C_MountJournal.Summon(0)
]])

-- add visual stuff here

SetOverrideBinding(button, false, "CTRL+`", "CLICK MyAwesomeMountButton:LeftButton")
