# Tmux Key bindings

**The prefix key** (`Ctrl+B` by default) activates Tmux commands. Press it, release, then press the command. For example, `Ctrl+B` then `c` creates a new window. Change the prefix in `~/.tmux.conf` with `set-option -g prefix C-a`.

Common key bindings (prefix = `Ctrl+B`):

Sessions:
```
prefix d            detach session
prefix s            choose session
prefix (            previous session
prefix )            next session
prefix $            rename session
```

Windows:
```
prefix c            create window
prefix n            next window
prefix p            previous window
prefix l            last window
prefix w            choose window
prefix ,            rename window
prefix &            kill window
```

Panes:
```
prefix "            split vertically (top/bottom)
prefix %            split horizontally (left/right)
prefix o            next pane
prefix ;            last pane
prefix x            kill pane
prefix z            toggle zoom (fullscreen pane)
prefix q            show pane numbers
prefix {            swap with previous pane
prefix }            swap with next pane
```

View all bindings: `tmux list-keys`. Create custom bindings in `~/.tmux.conf`:

```
bind-key -n C-l send-keys -R 'clear' Enter  # Ctrl+L to clear screen (no prefix needed)
```

Use `-n` flag for bindings that don't need the prefix.
