When first starting out using vim, I was nervous that I'd get lost in some foreign mode that could potentially wreak havoc. I felt like there was never really any "safety net" preventing me from a major blunder, possibly leading to a catastrophe with either my system or the file I was working on.
I've built up my own personal confidence, but surely there might be other beginners who feel the same way I did when starting out. Are there safeguards that can be put in place for someone learning the ropes? Any type of sandboxing, restrictions, or safety features would be ideal.
