So I was trying to modify one of my aliases to access a website quicker; and rather than type out a long line of code twice I tried to use an alias which I named $4chan_boards.
Anyway, long story short, the alias didn't work unless I took the number off. (In the end I just used a variable for easier modification.)
Now I'm not sure if this a bug or not because of the whole $0, $1, ... number identifiers but I thought I'd mention it.
