Working with tmux

The main trick for using tmux, is the prefix key for its all commands.

What is the prefix key?

the prefix is C-b by default.

Hah? what does that mean?

• the C- means press and hold the Ctrl key

• the b means press the b key

now it makes sense, you need to hold the Ctrl key and then press the b button. this is just the prefix, after that you could press different shortcuts. here is a simple shortcut for creating a new window in current session.

C-b c

do you get that? press and hold the Ctrl key and then press b, after that release the Ctrl key and immediately press the c key. Now you should see two windows in your status bar like below.

Now it’s time to move on and learn tricky shortcuts.
