            <p>Often times, when I run a vim command that makes &#8220;big&#8221; changes to a file (a
macro or a <code>:vimgrep</code> command) I lose my original position and feel disoriented.</p>

<p><em>Save position with <code>winsaveview()</code>!</em></p>

<p>The <code>winsaveview()</code> command returns a <code>Dictionary</code> that contains information
about the view of the current window. This includes the cursor line number,
cursor coloumn, the top most line in the window and a couple of other values,
none of which concern us.</p>

<p>Before running our command (one that jumps around the buffer, a lot), we save
our view, and restore it once its done, with <code>winrestview</code>.</p>

<pre><code>let view = winsaveview()
s/\s\+$//gc              &quot; find and (confirm) replace trailing blanks
winrestview(view)        &quot; restore our original view!
</code></pre>

<p>It might seem a little overkill in the above example, just use &#8220; (double
backticks) instead, but it comes in handy when you run your file through
heavier filtering.</p>
