Tip #1: The Backslash 1
You know that key on your keyboard, above the enter key. Yep, the backslash. Every time you think about pressing it, don’t. Don’t ever press it without holding down the shift key. Never ever ever. That’s all there is to it.
If the pipe didn’t share the same key, I’d tell you to rip it off your keyboard. Or at least, make a huge ball of duct tape and stick on top.



that wud make it hard for me to write my regex!
