What is the best way to highlight the whole current line in VIM? In some IDEs I am able to set some sort of 20% opacity of the line I am editing, this is great to find where I am rather quickly.
To highlight the current line use
:set cursorline
To highlight the current column use
:set cursorcolumn
The visual appearance of this can be modified. Have a look around :help hl-CursorLine
or hl-CursorColumn
.
