Is is possible to open a new-window with its working directory set to the one I am currently in. I am using zsh, if it matters.

Method 1
The current (1.9a) Tmux man page lists an optional -c start-directory parameter for some commands, including new-window and split-window.
It also contains the format variable pane_current_path, which refers to the
Current path if available.
By combining these, we can open a new window with the current working directory using
new-window -c "#{pane_current_path}"
The quotation are needed in case the current path contains spaces.
If you want to split the current pane vertically, use
split-window -c "#{pane_current_path}"
or, for a horizontal split
split-window -h -c "#{pane_current_path}"
To make the key bindings open new splits and windows with the current working directory by default, add the following to your .tmux.conf. The " with surrounding quotes is to tell Tmux it shouldn’t start a string but rather bind the " key.
bind '"' split-window -c "#{pane_current_path}"
bind % split-window -h -c "#{pane_current_path}"
bind c new-window -c "#{pane_current_path}"
Method 2
Starting in tmux 1.9 the default-path option was removed, so you need to use the -c option with new-window, and split-window (e.g. by rebinding the c, ", and % bindings to include
-c '#{pane_current_path}'). See some of the other answers to this question for details.
A relevant feature landed in the tmux SVN trunk in early February 2012. In tmux builds that include this code, tmux key bindings that invoke new-window will create new a window with the same current working directory as the current pane’s active processes (as long as the default-path session option is empty; it is by default). The same is true for the pane created by the split-window command when it is invoked via a binding.
This uses special platform-specific code, so only certain OSes are supported at this time: Darwin (OS X), FreeBSD, Linux, OpenBSD, and Solaris.
This should be available in the next release of tmux (1.7?).
With tmux 1.4, I usually just use
tmux neww
in a shell that already has the desired current working directory.
If, however, I anticipate needing to create many windows with the same current working directory (or I want to be able to start them with the usual <prefix>c key binding), then I set the default-path session option via
tmux set-option default-path "$PWD"
in a shell that already has the desired current working directory (though you could obviously do it from any directory and just specify the value instead).
If default-path is set to a non-empty value, its value will be used instead of “inheriting” the current working directory from command-line invocations of tmux neww.
The tmux FAQ has an entry titled “How can I open a new window in the same directory as the current window?” that describes another approach; it is a bit convoluted though.
Method 3
Yes, use new-window -c "#{pane_current_path}". You can add the following to your ~/.tmux.conf to make it persistent (assumming default keybindings):
bind c new-window -c "#{pane_current_path}"
bind '"' split-window -c "#{pane_current_path}"
bind % split-window -h -c "#{pane_current_path}"
The default-path path setting was removed from upstream code and tmux author recommended in that commit message using either -c "#{pane_current_path}" or -c "$PWD in the new-window and split-window commands.
I also answered in this duplicate question.
Method 4
With recent versions of tmux (v1.8, but maybe in v1.7 too):
tmux new-window -c "$PWD"
Method 5
The other answers does not work for me when I try put them as bindings (specifically tmux split-window -c). But I’ve made up my own solution that I’ve been using for more than a year that works for both new-window and splits:
~/.bashrc:
PS1="$PS1"'$([ -n "$TMUX" ] && tmux setenv TMUXPWD_$(tmux display -p "#D" | tr -d %) "$PWD")'
~/.tmux.conf:
unbind-key c bind-key c run-shell 'tmux new-window "cd "$(tmux show-environment $(echo "TMUXPWD_#D" | tr -d %) | sed -e "s/^.*=//")"; exec $SHELL"' bind-key C new-window bind-key - run-shell 'tmux split-window -v "cd "$(tmux show-environment $(echo "TMUXPWD_#D" | tr -d %) | sed -e "s/^.*=//")"; exec $SHELL"' bind-key | run-shell 'tmux split-window -h "cd "$(tmux show-environment $(echo "TMUXPWD_#D" | tr -d %) | sed -e "s/^.*=//")"; exec $SHELL"
Works, at least, with $(tmux -V) 1.8. See out-commented lines here for a version working for older tmuxes that don’t have the show-environment command.
Method 6
tmux did that in version 1.8 but in 1.9 this feature was removed in favor of using -c flag.
This can be solved but re-binding new-window but in case you want to run something else it becomes too wordy: instead of typing neww man tmux you’ll have to type neww -c "#{pane_current_path}" man tmux which you most probably don’t want to do.
There’s a mod of tmux (I’m the author) to add a proper scripting language to tmux to allow using aliases, binding multiple commands in ‘mode’, variables, loops, etc…
And also, it brings back the that behavior: new windows and panes are opened in the current directory.
It can be built from sources here: http://ershov.github.io/tmux/
