Unne's responses are pretty user-specific. I use ctrl-c/v expertly, and I have no problem fixing my typos by retyping words over and over and over and over instead of taking the time to use the insert function.

I also don't typically use scroll lock (what does it even do?) either. Whenever I see a flowing mess of code/output, I hit the pause button. There's a 'SysRq' under my Prt Scr key. I don't know what that does either. There's a weird button to the left of my right ctrl button that seems to do what right clicking does. I don't use that either. I also don't use the right windows key...

Ah forget it. If I had my way the keyboard would only have 95 keys and would look too odd.
