[TC 3.3.5a] Adding back the keybinding tooltip to a custom MainMenuMicroButton edit

[Kobiesan]

I recently made a FrameXML edit and patch that opens up the achievement frame at level 1. Only problem is that when you hover over the achievements button it will only say 'Achievements' and not 'Achievement (your keybinding for achievements)' does anyone know how to solve this? Here is my new MainMenuMicroButton.lua

function LoadMicroButtonTextures(self, name)
	self:RegisterForClicks("LeftButtonUp", "RightButtonUp");
	self:RegisterEvent("UPDATE_BINDINGS");
	local prefix = "Interface\\Buttons\\UI-MicroButton-";
	self:SetNormalTexture(prefix..name.."-Up");
	self:SetPushedTexture(prefix..name.."-Down");
	self:SetDisabledTexture(prefix..name.."-Disabled");
	self:SetHighlightTexture("Interface\\Buttons\\UI-MicroButton-Hilight");
end

function MicroButtonTooltipText(text, action)
	if ( GetBindingKey(action) ) then
		return text.." "..NORMAL_FONT_COLOR_CODE.."("..GetBindingText(GetBindingKey(action), "KEY_")..")"..FONT_COLOR_CODE_CLOSE;
	else
		return text;
	end
	
end

function UpdateMicroButtons()
	if ( CharacterFrame:IsShown() ) then
		CharacterMicroButton:SetButtonState("PUSHED", 1);
		CharacterMicroButton_SetPushed();
	else
		CharacterMicroButton:SetButtonState("NORMAL");
		CharacterMicroButton_SetNormal();
	end
	
	if ( SpellBookFrame:IsShown() ) then
		SpellbookMicroButton:SetButtonState("PUSHED", 1);
	else
		SpellbookMicroButton:SetButtonState("NORMAL");
	end

	if ( PlayerTalentFrame and PlayerTalentFrame:IsShown() ) then
		TalentMicroButton:SetButtonState("PUSHED", 1);
	else
		TalentMicroButton:SetButtonState("NORMAL");
	end

	if ( QuestLogFrame:IsShown() ) then
		QuestLogMicroButton:SetButtonState("PUSHED", 1);
	else
		QuestLogMicroButton:SetButtonState("NORMAL");
	end
	
	if ( ( GameMenuFrame:IsShown() ) 
		or ( OptionsFrame:IsShown()) 
		or ( AudioOptionsFrame:IsShown()) 
		or ( InterfaceOptionsFrame and InterfaceOptionsFrame:IsShown()) 
		or ( KeyBindingFrame and KeyBindingFrame:IsShown()) 
		or ( MacroFrame and MacroFrame:IsShown()) ) then
		MainMenuMicroButton:SetButtonState("PUSHED", 1);
	else
		MainMenuMicroButton:SetButtonState("NORMAL");
	end

	if ( PVPFrame:IsShown() ) then
		PVPMicroButton:SetButtonState("PUSHED", 1);
	else
		PVPMicroButton:SetButtonState("NORMAL");
	end
	
	if ( FriendsFrame:IsShown() ) then
		SocialsMicroButton:SetButtonState("PUSHED", 1);
	else
		SocialsMicroButton:SetButtonState("NORMAL");
	end

	if ( LFGParentFrame:IsShown() ) then
		LFGMicroButton:SetButtonState("PUSHED", 1);
	else
		LFGMicroButton:SetButtonState("NORMAL");
	end

	if ( HelpFrame:IsShown() ) then
		HelpMicroButton:SetButtonState("PUSHED", 1);
	else
		HelpMicroButton:SetButtonState("NORMAL");
	end
	
	if ( AchievementFrame and AchievementFrame:IsShown() ) then
		AchievementMicroButton:SetButtonState("PUSHED", 1);
	else
		AchievementMicroButton:SetButtonState("NORMAL");
	end
	-- Keyring microbutton
	if ( IsBagOpen(KEYRING_CONTAINER) ) then
		KeyRingButton:SetButtonState("PUSHED", 1);
	else
		KeyRingButton:SetButtonState("NORMAL");
	end
end

function HasCompletedAnyAchievement() return true
