Read my previous part of “tmux in practice” series for more details: tmux in practice: iTerm2 and tmux integration.Īnother tmux’s default I would prefer to change is the mouse wheel scroll. So ⌘↑ pressed in iTerm just sends M-Up keystroke to tmux session. It’s possible by using custom iTerm profile with some keybindings overridden to trigger tmux actions. Moreover, even when I’m inside tmux session, I can still continue using ⌘↑ and ⌘↓ to control the inner tmux scrollback buffer, rather that iTerm’s one. # Scroll up/down by 1 line, half screen, whole screenbind -T copy-mode-vi M-Up send-keys -X scroll-upbind -T copy-mode-vi M-Down send-keys -X scroll-downbind -T copy-mode-vi M-PageUp send-keys -X halfpage-upbind -T copy-mode-vi M-PageDown send-keys -X halfpage-downbind -T copy-mode-vi PageDown send-keys -X page-downbind -T copy-mode-vi PageUp send-keys -X page-up The usual PageDown and PageUp controls are available to scroll by whole screen, and extra M-PageDown and M-PageUp to scroll by a half of screen (really convenient). Once you’re in copy mode, you can continue pressing M-Up to scroll 1 line up. I’ve gotten used to ⌘↑ to start scrolling in iTerm, and I’ve added following root keybinding: # trigger copy mode bybind -n M-Up copy-mode Personally, I use tmux scrollback without hacks above, but tweak it’s configuration to be more friendly and familiar.įirst of all, I don’t like prefix,[ to enter copy mode. And when you detach/close a tmux session, the parent terminal is polluted with tmux window’s output. However, this solution is limited to having tmux session with 1 window and 1 pane only. Some people who find this annoying - configure tmux scrollback buffer to be allowed to be shown up in parent terminal scrollback buffer - so they can just use familiar scrolling controls. The solution is to use tmux specific controls to access its own scrollback buffer: Ctrl-b then [ to enter copy mode, use Down/Up arrows or PageDown and PageUp keys, q or Enter to exit copy mode. In practice, if you get used to scroll back using ⌘↑ in your iTerm and if you’re going to do the same inside running tmux session, you will control and scroll the outer iTerm’s scrollback buffer, rather than the tmux’s inner scrollback buffer. When you close your full-screen app, you get back to the same state when you launched the app and don’t see output from inside the app any more. Any output produced inside tmux (the same is true for vim, nano, man, less, and so on) does not spill over into the outer terminal’s scrollback history.

The consequence of this is that you cannot work with tmux inner scrollback same as you usually do within your terminal.

To prevent history loss, tmux implements it’s own “inner” scrollback buffer. As soon as lines go out of view, they are lost. Any output, that exceeds visible part of alternate buffer, is lost.

There are several effects of using alternate buffer: Alternate buffer has exact width and height dimensions as physical window size. tmux, like other full-screen terminal applications like vim, runs in so-called alternate screen buffer of a parent terminal. Usually terminal emulators implement scrollback buffer, so you can explore past output, when it moves out of view. This is 3rd part of my tmux in practice article series.
