If you don't know which options you should use, you may be interested in the :options
command.
This will open a split with all Vim options listed and with their current value displayed. There are 26 sections to display all options you can try.
e.g.
4 displaying text
scroll number of lines to scroll for CTRL-U and CTRL-D
(local to window)
set scr=20
scrolloff number of screen lines to show around the cursor
set so=5
wrap long lines wrap
set nowrap wrap
...
On a value line (e.g. set nowrap
) you can press CR to toggle the value (if it's a binary value).
On an option line (e.g. wrap long line wrap
) you can press CR to access the documentation for this option.
