[Tex/LaTex] Word-wrap in TeXmaker editor (how to NOT have a whole paragraph as one line)

texmakerwrap

I am new to LaTeX and am using TeXmaker on Windows 7.
Now, I would like to know how to wrap text in this software. Because now I have written a whole paragraph, which, however, has only one line number.
(See the example – the whole paragraph is line 1)

I tried the solution in this answer, I went to User -> Run script -> hardwordwrap_selection_80col – but it (as name suggests) only works on a selection.

Is there any way to make it work for the whole document?
