vim中的位置列表和quickfix列表有什么区别

以下内容来自有关quickfix列表和位置列表的文档.但我不确定究竟有什么不同.下图显示了位置列表和quickfix列表中的相同内容.我什么时候在vimgrep和lvimgrep中使用一个或另一个.

In Vim the quickfix commands are used more generally to find a list of positions 
in files.For example, |:vimgrep| finds pattern matches.  You can use the positions 
in a script with the |getqflist()| function. Thus you can do a lot more than the
edit/compile/fix cycle!

                         *location-list* *E776* 
A location list is similar to a quickfix list and contains a list of positions 
in files.  A location list is associated with a window and each window can have 
a separate location list.  A location list can be associated with only one window.  
The location list is independent of the quickfix list.

UPDATE

我从这里找到了以下内容.

These commands all fill a list with the results of their search. "grep" and 
"vimgrep" fill the "quickfix list", which can be opened with :cw or :copen, 
and is a list shared between ALL windows. "lgrep" and "lvimgrep" fill the 
"location list," which is local to the current window, and can be opened 
with :lw or :lopen. Both of these lists can be used to instantly jump to 
the matching line in whatever file it occurs in.

所以区别在于所有用于quickfix列表的窗口和用于位置列表的本地窗口.但是我可以从任何其他窗口打开位置列表.那么有什么不同呢？
