Here are some LaTeX tricks I have found.

# TikZ-cd arrows in TikZ

If you want to style an arrow in TikZ the same way it is styled in TikZ-cd, you can do

`\draw [commutative diagrams/.cd, every arrow] (0, 0) -- (0, 1);`

You can similarly add attributes, such as `dashed`

:

`\draw [commutative diagrams/.cd, every arrow, dashed] (0, 0) -- (0, 1);`

# QED symbol for theorem without proof

The following command inserts a qed symbol at the end of the line, as if `\qedhere`

was used, and works in any environment:

`\newcommand\fakeqed{\pushQED{\qed}\qedhere}`
