We want to have a nice experience when scrolling the terminal buffer using both alacritty and tmux on Debian linux.
When we run alacritty and tmux together and there's a lot of text on the screen (say, by invoking tree), we need to hit the following tmux key sequence to scroll back through the terminal history:
Ctrl+B
[
PageUp
This is difficult. Others have asked about this.
We followed the workaround advice given by the author. We enabled mouse mode, and disabled faux scrolling in .tmux.conf:
set -g mouse on
set -ga terminal-overrides ',*256color*:smcup@:rmcup@'
In .alacritty.conf, the default scrolling key combination, Shift+PageUp, isn't too bad. We can just leave it commented to use it, but if we want to try our own settings, we can:
key_bindings:
#
# ...snip...
#
- { key: PageUp, mods: Shift, action: ScrollPageUp, mode: ~Alt }
- { key: PageDown, mods: Shift, action: ScrollPageDown, mode: ~Alt }
- { key: Home, mods: Shift, action: ScrollToTop, mode: ~Alt }
- { key: End, mods: Shift, action: ScrollToBottom, mode: ~Alt }
Resolution
With the changes to .tmux.conf, we can now start an alacritty terminal, enter tmux, and scroll to our hearts' content, without using a difficult key combination.
🔥 It's FAST! 🔥
We found that scrolling through history with some basic command line apps wasn't negatively impacted.
When we entered tmux + alacritty, and then dumped a lot of text into less, or navigated man bash, we scrolled happily and without interruption.
These instructions probably apply to other terminal emulators, as well.
This is a happy time. 😄

nice. thanks a bunch @terkwood ... really need this solution. it works also on WSL2 windows 10
The mouse scroll works, but
does nothing.
And those key binding do not work for
man bashorless.Looks like the key bindings in alacritty need to be left alone, while .tmux.conf needs
