You just have to be fairly cautious, though it helps if you're able to spell, too. Sometimes I fail at spelling so I have to use backspace just to spell properly :{ (hasn't happened so far in this post yet, though, so yay.)

I'll try typing as fast as I can now to see how long it'll take for me to have yto

there. :}
