OK, this is quite a small tip but maybe useful sometimes, for example, I got this when I was formatting a blog into 80 columns width.

It’s quite convenience if I can just goto column 80 directly by pressing a key or a key-binding rather than stroke f/F, w/e several times.

So here it is: the magic key is |, yes, the separator key, not the I or l character.

For example, to jump to 80 column in vim, just press below keys in normal mode.
