Bumping because GetBindingText is protected now. Can't figure out what to do.
Edit: Secure hook ActionButton_UpdateHotkeys and do something like this:
Code:
local function styleHotKeys(self, actionButtonType)
local ho = _G[self:GetName().."HotKey"]
local text = ho:GetText()
text = text:replace( "-", "" )
text = text:replace( "Mouse Wheel Down", "WD" )
text = text:replace( "Mouse Wheel Up", "WU" )
ho:SetText(text)
end
