1076 How does one insert a "\" (backslash) into the text of a LaTeX document? And how does one insert a "~" (tilde)? (If you insert \~, it will give you a tilde as an accent over the following letter.) I believe \backslash may be used in math formulae, but not into text itself.
There is no difference between LaTex and Overleaf. Overleaf uses LaTex. You write LaTex documents in Overleaf. Whenever you have a problem with your document not looking like it should, yo can do a web search for LaTex, and you can apply all information you get regarding LaTex in Overleaf, because thats what Overleaf is.
I use the "LaTeX => DVI" option. I am a newbie to LATeX, so I do not know the difference between "LaTeX => PDF" and "LaTeX => PS => PDF" My ultimate goal is to convert the document into a pdf file.
