 ===== Multiple windows =====
-By default, a Tmux session starts with only one window. You can create more by typing CTRL-b c. All windows have a numeric id, and start named as the current shell or command being run. To rename the current window, type CTRL-b ,. Then you can switch between windows typing CTRL-b number, where number is the number of a window. CTRL-b n and CTRL-b p are both shortcuts to, respectively, the next and previous window.

+===== Emulating Emacs-like registers =====
+If you have a need for multiple clipboard-like buffers for storing and retrieving text (akin to registers in Emacs or Vim), Tmux already supports that, although this functionality is not well exposed by default. Below is a sample piece of configuration that makes available 26 registers designated by single lower-case letters //a-z//.
+<file>
+# Initialize alphanumerical registers to avoid the problem with 'delete-buffer'
+run "tmux set-buffer -b a \"$(echo ' ')\""
+run "tmux set-buffer -b b \"$(echo ' ')\""
+run "tmux set-buffer -b c \"$(echo ' ')\""
+run "tmux set-buffer -b d \"$(echo ' ')\""
+run "tmux set-buffer -b e \"$(echo ' ')\""
+run "tmux set-buffer -b f \"$(echo ' ')\""
+run "tmux set-buffer -b g \"$(echo ' ')\""
+run "tmux set-buffer -b h \"$(echo ' ')\""
+run "tmux set-buffer -b i \"$(echo ' ')\""
+run "tmux set-buffer -b j \"$(echo ' ')\""
+run "tmux set-buffer -b k \"$(echo ' ')\""
+run "tmux set-buffer -b l \"$(echo ' ')\""
+run "tmux set-buffer -b m \"$(echo ' ')\""
+run "tmux set-buffer -b n \"$(echo ' ')\""
+run "tmux set-buffer -b o \"$(echo ' ')\""
+run "tmux set-buffer -b p \"$(echo ' ')\""
+run "tmux set-buffer -b q \"$(echo ' ')\""
+run "tmux set-buffer -b r \"$(echo ' ')\""
+run "tmux set-buffer -b s \"$(echo ' ')\""
+run "tmux set-buffer -b t \"$(echo ' ')\""
+run "tmux set-buffer -b u \"$(echo ' ')\""
+run "tmux set-buffer -b v \"$(echo ' ')\""
+run "tmux set-buffer -b w \"$(echo ' ')\""
+run "tmux set-buffer -b x \"$(echo ' ')\""
+run "tmux set-buffer -b y \"$(echo ' ')\""
+run "tmux set-buffer -b z \"$(echo ' ')\""
+</file>
+<file>
+# Copy to user-selected register
+bind -T copy-mode r command-prompt -1 -p '(register)' 'delete-buffer -b %1 ; send -X copy-pipe "tmux set-buffer -n %1"'
+# Paste from user-selected register
+bind -T prefix C-] command-prompt -1 -p '(register)' 'paste-buffer -b %1'
+</file>
+The way it works is this: when in //copy-mode// you get an additional key binding //r// which prompts you for a single-letter named register in which to store the marked region. In normal mode you get a prefix command //C-b C-]// which prompts for the name of the register whose contents will be pasted at the cursor. You can also list the contents of all buffers by running //C-b :list-buffers//. Manual initializing of all the buffers seems necessary, because otherwise //delete-buffer// complains about trying to delete a nonexistent buffer when used for the first time for a given letter.
+===== Troubleshooting Colors =====
+If colors are not working in your tmux session try running tmux with the -2 flag.
+''$ tmux -2''
+To persist 256color support in your terminal you can add the following line to your ~/.bashrc
+''TERM=screen-256color''
