How to force internet recovery on Mac osx

Although Mac osx is very stable, sometimes thing go wrong. And Murphy's law suggests it goes wrong on the worst possible time. Recently my Mac start being very very slow and irresponsive. I tried to check disk permission and first aid. Ther e were bunch of permission issues, I fixed all but one. I searched for the remaining one online and found that it it not important yet my Mac runs extremely slow. So I decided to format it. You can boot from recovery partition if you configured one by holding alt key on boot up. But in my case even recovery partition was unusably slow. So I searched and found a short cut for internet recovery,

Press option+command+r on boot up and you will go to internet recovery

If you press command+r it will point you to recovery partition or internet depending on whether or not recovery partition is configured.

I hope you don't need to use this. In case you needed I hope it helps.
