-The function opens an `ssh` connection to the server specified then attempts to attach an existing `tmux` session. If this fails it will try to start a new session. If both of those commands fail, if `tmux` isn't installed for example, then it falls back to normal `ssh`

-Living inside a `tmux` session then using `tmux` over `ssh` meant I had to use two different prefix options. I didn't like this. I use the backtick as my prefix in `tmux` because I am lazy. I wanted to use the same backtick prefix on my remote sessions. This worked if I hit backtick twice before the command I wanted to send to the remote, or "second" session.

With a bit of internet searching I found a discussion on the [tmux Github page](https://github.com/tmux/tmux/issues/237){target="_blank" rel="noreferrer"} regarding a toggle option. I also came across [bnorick's tmux.conf](https://github.com/bnorick/tmux-config/blob/master/tmux/tmux.conf#L368){target="_blank" rel="noreferrer"} with a toggle for nested sessions.

When I hit F12 the prefix in my local session is set to None, then I change the colour of the active window tab in the status bar so I remember it is disabled. I can now use the backtick prefix freely in my remote session. To enable the local session again I hit F11.
