Deleting History items and items in dropdowns (#delete)

Deleting History items

To clear when it shows up on the location bar autocomplete search ("AwesomeBar"), move cursor over the line so that it highlights then press the Del key.  Items with Stars are bookmarks, items with tag icons are icons, both are bookmarks and the bookmarks will not be deleted in this manner from the location bar dropdown.

From History (Ctrl+H) and from a search from History click to the left of the icon, once selected press Del key.

To delete multiple selected items, you can Ctrl+click separately on several items before using Del.  If you have a range you can use Shift+click to extend a selection, or from a restrictive search you can use Ctrl+A to select all before using Del key.

Deleting Bookmark items

Should be much the same as the above.  From Bookmarks Sidebar (Ctrl+B) or from "Organize Bookmooks" (in Places it is Library listing from bookmarks menu or from Ctrl+Shift+B).
