Recently I was sshed into my home pi server trying to sftp some big files from a remote server.
Some of the transfers are huge, 30gb+. On our internet that will take a while. Not
wanting to leave the shh terminal session open that whole time I used
[screen](https://linux.die.net/man/1/screen) on the pi.
Idea was to create a screen session start the transfer detach and comeback few hours later.
Detaching was a bit tricky. <Ctrl\><a\> <d\> is the default detach command for both tmux running on my
mac and screen running on the pi. So when I tried to detach from the screen session tmux would
detach instead. 😡

After messing with configs and some searching turns out if you press the tmux prefix key twice it
sends it once to the child shell. So eventually I was able to detach from the screen session with:

**<Ctrl\><a\> <Ctrl\><a\> <d\>**!!
