How can I type curly and square braces on this phone?

Actually, when I press the symbol button on the touch keyboard of the LG G3, I don't see a way to type {, }, [, or ]. How can I type these characters?

I answered my own question. There is a left and right arrow key that I thought were the actual symbols for left and right arrow. Instead, this increments through two extra symbol boards. Not obvious to me, but there it is in case anyone else has the same question I did.
