How do I define the amount of vertical space there are after all new lines? I am looking for something that works like this:
\define{x = 4}
blah blah blah blah \\[x pt]
blah blah \\[x pt]
Where I can with one modification change the amount of vertical space after all new lines. I don't care whether it uses \\, \newline, \linebreak, or something else.
\def\myvar{4}
then your code follows\\[<length>]
to start a new line. See this: tex.stackexchange.com/questions/198824/… and this: tex.stackexchange.com/questions/82664/… and also this: tex.stackexchange.com/questions/198299/… for more discussions on this.
