+# tmux(1)
+
+Terminology:
+- `session` is a collection of pseudo terminals which can have multiple
+  `windows`
+- `window` uses the entire screen and can be split into rectangular `panes`
+- `pane` is a single pseudo terminal instance
+
+# Tmux cli
+```markdown
+# Session
+tmux                        creates new session
+tmux ls                     list running sessions
+tmux kill-session -t <s>    kill running session <s>
+tmux attach -t <s> [-d]     attach to session <s>, detach other clients [-d]
+tmux detach -s <s>          detach all clients from session <s>
+
+# Environment
+tmux showenv -g             show global tmux environment variables
+tmux setenv -g <var> <val>  set variable in global tmux env
+
+# Misc
+tmux source-file <file>     source config <file>
+tmux lscm                   list available tmux commnds
+tmux show -g                show global tmux options
+tmux display <msg>          display message in tmux status line
+```
+## Scripting
+```markdown
+# Session
+tmux list-sessions -F '#S'           list running sessions, only IDs
+
+# Window
+tmux list-windows -F '#I' -t <s>     list window IDs for session <s>
+tmux selectw -t <s>:<w>              select window <w> in session <s>
+
+# Pane
+tmux list-panes -F '#P' -t <s>:<w>   list pane IDs for window <w> in session <s>
+tmux selectp -t <s>:<w>.<p>          select pane <p> in window <w> in session <s>
+
+# Run commands
+tmux send -t <s>:<w>.<p> "ls" C-m    send cmds/keys to pane
+tmux run -t <p> <sh-cmd>             run shell command <sh-cmd> in background and report output on pane -t <p>
+```
+
+For example cycle through all panes in all windows in all sessions:
+```bash
+# bash
+for s in $(tmux list-sessions -F '#S'); do
+    for w in $(tmux list-windows -F '#I' -t $s); do
+        for p in $(tmux list-panes -F '#P' -t $s:$w); do
+            echo $s:$w.$p
+        done
+    done
+done
+```
+
+# Bindings
+
+```markdown
+prefix d    detach from current session
+prefix c    create new window
+prefix w    open window list
+prefix $    rename session
+prefix ,    rename window
+prefix .    move current window
+```
+
+Following bindings are specific to my [`tmux.conf`](https://github.com/johannst/dotfiles/blob/master/tmux.conf):
+```markdown
+C-s         prefix
+
+# Panes
+prefix s    horizontal split
+prefix v    vertical split
+prefix f    toggle maximize/minimize current pane
+
+# Movement
+prefix Tab  toggle between window
+
+prefix h    move to pane left
+prefix j    move to pane down
+prefix k    move to pane up
+prefix l    move to pane right
+
+# Resize
+prefix C-h  resize pane left
+prefix C-j  resize pane down
+prefix C-k  resize pane up
+prefix C-l  resize pane right
+
+# Copy/Paste
+prefix C-v    enter copy mode
+prefix C-p    paste yanked text
+prefix C-b    open copy-buffer list
+
+# In Copy Mode
+v     enable visual mode
+y     yank selected text
+```
+
+# Command mode
+
+To enter command mode `prefix :`.
+
+Some useful commands are:
+```markdown
+setw synchronize-panes on/off       enables/disables synchronized input to all panes
+list-keys -t vi-copy                list keymaps for vi-copy mode
+```
