How to edit OOB(out of box) Pages of SharePoint in IE

Here is the following Steps to edit OOB pages of SharePoint in IE or without SharePoint Designer

E.g. : I want to edit the "Allitems.aspx" OOB  page of document library.

1.  Open the Allitems.aspx page in IE. e.g. "http:/localhost/Documents/Forms/AllItems.aspx"
2.  Add the following text after the URL "?PageView=Shared&ToolPaneView=2" e.g "http:/localhost/Documents/Forms/AllItems.aspx?PageView=Shared&ToolPaneView=2"
3. It will open the OOB page in edit mode.
