9.22.2.2 Not equal sign (a^\211 ) with a vertical bar

https://tex.stackexchange.com/landing/r/digest?cta=question&id=108193

9.22.2.3 Crop an inserted image?

9.22.2.5 The \bar and \overline commands

https://tex.stackexchange.com/landing/r/digest?cta=question&id=22100

I want to represent, say, the closure of a set or the extended reals, e.g., $\bar{\mathbb{R}}$ but unfortunately this creates a bar that is much too small (horizontally) and can barely be seen. On the ...

9.22.2.6 How to add an empty line between paragraphs?

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?

9.22.2.7 Command for argmin or argmax?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=5223

How can you get the argmin or argmax in Latex? Two solutions I found are: 
\underset{x}{\operatorname{argmax}} 
\DeclareMathOperator*{\argmin}{arg\,min} 
Any other ideas?
