.bash_profile

### If using iTerm2 powershell was not getting my colors right...
alias tmux="tmux -2"

.tmux.conf

set -g default-terminal "screen-256color"

unbind C-b
set -g prefix C-a
set-window-option -g mode-keys vi
bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R

## So we can now use Ctrl-a + a To begin of line in bash / vim
bind a send-prefix

set -g history-limit 5000

.vimrc
