By setting 'wrap' on, you will see as much of the current line as fits
in the current window ("window" in the Vim sense, there may be one or
more windows in a single Vim). Then you can scroll the text (by means
of the down-arrow key or, in Normal mode, by Ctrl-E) to display any
part of the current file line that overflow the current line. To get
at the next equal sign (if any), but only on the current line
(including any part of it overflowing the screen), use
f=
("forward to =", see ":help f"); or to go to the end of the line,
scrolling if necessary, use the <End> key or, in Normal mode, the $
key.
Best regards,
