First off let me say this is my first post here hopefully I got it in the correct section. If you think it's lame sorry, just trying to be a contributing member and this process worked for me. This is very similar to the Time-Lost Proto Drake button smasher though the work is my own and can be used for anything you need to mash a button for. With that said it's a super simple macro posted below are the details:
Loque'nahak is an exotic hunter pet with an interesting skin, have to be 51 point BM hunter to get. And ya dps with the talent spec to tame is lower but for some of us we just have to have him:

If this helps someone like it did me, great. If the overall feeling is that it's trash then a mod can delete the post maybe =)
You need AutoIt.
Code:
WinWaitActive("World of Warcraft")
Global $UnPaused
HotKeySet("{F1}", "TogglePause")
HotKeySet("{F2}", "Terminate")
While 1
Sleep(100)
ToolTip("Script is Paused",0,0)
WEnd
Func TogglePause()
$UnPaused = NOT $UnPaused
While $UnPaused
ToolTip("Sending...",0,0)
Send("a")
Sleep(1000)
WEnd
EndFunc
Func Terminate()
Exit 0
EndFunc
1. Create a macro in wow
2. Open wow, type /macro
3. Select a new, pick an icon, give it a name and paste the follow text into it (I choose the stomping wave file so I wouldn't give my family nightmares when it went off at 3am).
Code:
/tar Loque
/tar King
/tar Aoto
/stopmacro [noexists]
/w yourname >%t<
/script PlaySoundFile("Sound\\Character\\Footsteps\\mFootHugeGiantDirtA.wav")
4. Place the new macro on your hotbar and assign it to the a button (You can change it to whatever you want if you modify it in the script above, I used the a key).
5. Choose a camp location, I've circled my favorite below. I like this spot because two of the rares spawn here. King Krush and Loque'nahak, both of which are rare and tamable. Despite what people say King Krush can be solo tamed.

6. Start Macro and wait, I stay on my flying mount so that I won't get agro from anything else.
Notes about Macro:
F1 pauses and unpauses (Nice for when you need to chat)
F2 closes macro
"A" Key is what is spammed by default
Details about Loque'nahak: Loque'nahak - NPC - World of Warcraft
Spawn details (Some of which are debatable)
1. 6ish hour spawn timer (though some have seen as quickly as an hour after the last rare kill)
2. 7ish spawn locations
3. Can't be up when one of the other two rares are up in the zone (King Krush, Aotona)
Paired with Glider/Yoink you could have a fully automated travel/search bot.
