Left ignition on overnight. Anything to be wary of?

I have a 2000 Ford Focus 1.6 and last night, I needed to move it forward a bit but I also needed to turn the wheels a bit so I put the ignition on but didn't start the engine (I don't like turning it on and then straight off again), I then, stupidly, forgot to turn the ignition off. I realised this the next morning when I couldn't find my keys and saw they were still in the ignition of the car :o The battery was completely empty but me and my parents managed to push-start the car and then I drove for a bit to charge the battery back up. After this it seems to now start up absolutely fine. However, I was talking to a couple of people about my stupidity, and one person said I may have ****ered my ignition coil which has worried me a bit. Is there anything else I should be aware of? And yes, I know I'm an idiot :p

Thanks

Drove about 30 odd miles today so hopefully I won't have any problems in the morning! As long as I haven't worn, or reduced the life of something majorly by leaving the ignition on, then I can stop worrying about it.

Thought I'd spelt 'Wary' wrong. Shoulda googled it :p Can't seem to change the title now.

Thanks
 
Your mate who was talking about the coil was refering to old fashion coil's on cars as the coil's on cars are not like that anymore and don't burn out from leaving the ignition on too long. There is an "old wifes" tale about these old types of coil isn't there?

Well, on older cars, 'ignition on' was literal - you were just powering up the coil. I've always been told they can burn out if left on without being discharged during normal use, I've no idea how much truth is in it, but it makes sense I guess.
 
Older cars had "points" to switch the coil on and off to create the spark, these were opened and closed by the rotation of the engine so if you left the ignition on and the points were closed (engines almost always stopped with the points closed) then the coil would be powered up and would overheat. Modern electronic systems power down the coil if the engine isn't turning.

If your battery was tired before, completely discharging it might may spell it's imminent demise. I killed a relatively new (3 years old) battery in my Civic by leaving the lights on, it wouldn't charge properly afterwards.
