It's quite simple really. F5 = Quicksave, F9 = Quickload. Every game developer should know this by now, no excuses.
Having played Rage recently, the lack of save was extremely apparent and frustrating and a major point against the game. Were I to review it, it would lose marks for not offering a save. What I don't get is how KotOR, Mass Effect and other BW titles have a simple, easy to use save feature on consoles, yet no other developer seems able to work out how to do it. Morons.
Has anyone played "Outcast" for the PC, a 10 or so year old title? It actually incorporated saving into the gameplay in a still unmatched, creative way. Must admit too, I kinda like the way ResiEvil4 did it too. I can save when I want, but not where...it in itself added an extra element of danger, wondering where the next point is.
Lastly, Dead Space 2 on Nightmare difficulty. Less difficult than the hardest difficulty but only three saves for the whole playthru. Turned them into tactical choices which themselves were the subject of much debate. It changed the way the game was played on other difficulties, ammo was significantly more valuable, every step much more tense. I think it was a very well thought out and implemented challenge with a cool reward on offer and I still remember my playthru for it. I'm glad it was an optional thing tho, don't think I could do it again.
