When you forget a binding in the middle of a session, you don't need to leave your terminal to look it up. tmux ships with built-in help commands that list every key binding, dump the current server state, and show live window information. These are the fastest way to rediscover shortcuts you haven't committed to muscle memory yet.

How do I see all tmux key bindings?
Press Ctrl+b ? or run tmux list-keys. Both open a scrollable list of every binding tmux currently has loaded, including any you defined in ~/.tmux.conf. Press q to close the list.
Why doesn't the prefix key work inside the key-binding list?
The list-keys view is a copy-mode buffer, so it responds to copy-mode navigation (arrows, Page Up/Down, or the mouse if mouse mode is on) rather than the tmux prefix. Press q when you're done reading.
How can I inspect the current tmux server state?
Run tmux info to print every session, window, pane, and attached client the server is tracking, along with build and platform details. It's the quickest way to confirm what tmux thinks is running before you script against it.
