Vim-Slime tmux integration (https://github.com/jpalardy/vim-slime)

1. Connect to tmux session/window/pane for each Vim session:
   • Leave tmux socket name set to default.
   • Target pane notes:
     • : - current window, current pane (a reasonable default)
     • :i - ith window, current pane
     • :i.j - ith window, jth pane
     • h:i.j - tmux session h (either session name or number), the ith window, and the jth pane
2. CTRL-c, CTRL-c - Send either the explicitly selected text, or the current paragraph (i.e. results of vip).
3. CTRL-c, v - Reset the tmux connection settings.

iTerm2 Integration

• Start tmux with tmux -CC to enable native iTerm2 window management of the tmux session. Works for local tmux sessions, or sessions on remote machines.

Reload tmux configuration

tmux source-file ~/.tmux.conf
