+* PERSPECTIVE
+Perspective provides multiple named workspaces (or "perspectives") in Emacs, similar to having multiple desktops in window managers like Awesome and XMonad.  Each perspective has its own buffer list and its own window layout, making it easy to work on many separate projects without getting lost in all the buffers.  Switching to a perspective activates its window configuration, and when in a perspective, only its buffers are available (by default).  Doom Emacs uses 'SPC some_key' for binding some of the perspective commands, so I used this binging format for the perspective bindings that I created..

 * REGISTERS
 Emacs registers are compartments where you can save text, rectangles and positions for later use. Once you save text or a rectangle in a register, you can copy it into the buffer once or many times; once you save a position in a register, you can jump back to that position once or many times.  The default GNU Emacs keybindings for these commands (with the exception of counsel-register) involves 'C-x r' followed by one or more other keys.  I wanted to make this a little more user friendly, and since I am using Doom Emacs, I choose to replace the 'C-x r' part of the key chords with 'SPC r'.
