tmux bug or single quotes (intentionally) required?

[Thomas Sattler]

Hi there ...

I'd like to bind Ctrl-End to select the rightmost window. It is
working fine when defining it at the commandline:

$ tmux lsk | grep -e C-End # not yet defined
$ tmux bind-key -T root C-End select-window -t :$
$ tmux lsk | grep -e C-End
bind-key -T root C-End select-window -t :$

The binding is also working as expected, but trying to put it
into my tmux.conf like this

bind-key -n C-End select-window -t :$

fails when starting tmux (or reloading config):

invalid or unknown command: bind-key -n C-End select-window -t :$

Using the alternative syntax (tmux-2.1 only)

bind-key -n C-End select-window -t :{end}

is working. Or a backward-compatible workaround via 'run':

run 'tmux bind-key -n C-End select-window -t :$'

Using double quote (") also fails:

bind-key -n C-End select-window -t ":$"

while single quote (') also works:

bind-key -n C-End select-window -t ':$'

Is/was this behaviour intended?

P.S.: Doing the same thing for Ctrl-Home to select :^ works.

$ is a special character so you should put it in single quotes.

I know $ is special in a shell, but what is so special about
it *inside* tmux.conf? The manpage mentions it several times:

- 18x as a prompt like this:

$ tmux attach OR $ printf '\033kWINDOW_NAME\033\\'

- twice as a hotkey for rename-session and in vi-mode

- twice as a prefix to a session ID

- once as a token for a window ID (this is what I did)

It is never mentioned that $ should be quoted in tmux.conf.
