[Emacs] Delete marked selections and remove toolbar

In Emacs you can't delete a marked buffer directly using the [DEL] button on the keyboard. In order to do that enable the M-x delete-selection-mode

Also, if you don't like the emacs toolbar get rid of it using M-x tool-bar-mode

Set the following in your ~/.emacs file

(custom-set-variables
  '(tool-bar-mode nil)
  '(delete-selection-mode t))
