# Set Up Forwarding Prefix For Nested Session
|
|
|
|
I use
|
|
[`ctrl-z`](https://github.com/jbranchaud/dotfiles/blob/main/config/tmux/tmux.conf#L57)
|
|
(instead of `ctrl-b`) for my tmux prefix key. I also have [`ctrl-z
|
|
ctrl-z`](https://github.com/jbranchaud/dotfiles/blob/main/config/tmux/tmux.conf#L138-L139)
|
|
configured to toggle back and forth between the previously visited window.
|
|
|
|
With that in mind, I needed to set up a specific keybinding to send the prefix
|
|
key to an inner (nested) tmux session. That's because sometimes, like with a
|
|
tool such as `overmind`, you can end up connected to a tmux session while
|
|
already within a tmux session.
|
|
|
|
So, I have `Ctrl-z a` send the prefix key to the inner tmux session. This is
|
|
what I added to my
|
|
[`tmux.conf`](https://github.com/jbranchaud/dotfiles/blob/main/config/tmux/tmux.conf#L167-L168):
|
|
|
|
```
|
|
# send prefix to inner tmux session (C-z a)
|
|
bind-key a send-prefix
|
|
```
|
|
|
|
Simply doing `Ctrl-z d` will detach me from the outer tmux session. If I want to
|
|
detach from an inner tmux session, I can use my new keybinding -- `Ctrl-z a d`.
