I am trying to insert the symbol in the title of the question, which I copied from a PDF article, but it appears as space in the output file. What is the corresponding LaTeX command?

9.7.2.2 Remove ugly borders around clickable cross-references and hyperlinks

https://tex.stackexchange.com/landing/r/digest?cta=question&id=823

I know that I can use hyperref to make cross-references and hyperlinks clickable.  That makes the clickable areas outlined in fluorescent green, however.  How can I make the green boxes go away? 
[hyperref] [color] [boxes] [links]

9.7.2.3 How to typeset subscript in usual text mode?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=1013

It's easy to make subscripts in math mode: $a_i$. 
How do I make a subscript outside math environment, likethis?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=54480

I have a basic tex file and a bibliography which is exported from Mendeley 
However, when I want to cite in the author-year style, I get the error: 
Package natbib Error: Bibliography not compatible ...

9.7.2.5 Changing the font size in a table

https://tex.stackexchange.com/landing/r/digest?cta=question&id=27097

What's the recommend way of changing the font size in a particular table? Is there a better way than enclosing all values with, for example, the \tiny function. 
[tables] [floats] [fontsize]

https://tex.stackexchange.com/landing/r/digest?cta=question&id=135134

I have two sections which I'd like to separate by an empty line. Every time I press Enter, LyX removes that empty line between paragraphs. How do I prevent this? 
[spacing] [lyx]
