How do I display/edit the machine name for a View?
You can export view, change values, delete original and import view back.

There is a import option in the views listing page. Just paste this url after your current url and you will see the import views page. By seeing your tags I am assuming you are using Drupal 7, so the given below url will work only for Drupal 7.

Below is the url to be added :

#overlay=admin/structure/views/import


To export view: 


go to /admin/structure/views 
under 'operations' column click on arrow and select 'export' 
copy code and edit/change in external editor 
go to /admin/structure/views/import and import changed view You can first delete existing view or select 'Replace an existing view if one exists with the same name' on the import settings –
