Standard keys for quick-load / quick-save

Is there a 'standard' key set-up for quick load and quick save? I seem to remember them being on F4 and F5 but I've seen them on F6 and F7 lately. Any opinions on which I should use?

I always assume f2 and f4 being the save and load keys, but i dont know.

Oh dear, that's a 3rd combination then :p

Guess I could do something like F2/F3/F4 are save, F5 to F7 are load, something like that.

Years ago, (like 15) I remember all games using f5 to save and f9 to load. But maybe they are still used, as Skyrim still uses those keys.

If that is what you are talking about...

Yeah, trying to remember what games usually use so I can use them, so it's a bit more intuitive. Unfortunately, I've just noticed that F5 and F6 seem to do something to Chrome anyway (F5 refreshes the page I think), so I can't use them. I'll just have to use my own keys and inform the player which keys they are.

Yeah, and the Alt key I believe is reserved too, cutting out a lot of options.
