Brilliant!

I commented out lines 25, 103 and 104 on OSX, as tmux exits immediately.

There is a typo in the "reload" command:

bind r source-file ~/.tmux.conf; display "Reloaded"

The ";" should be escaped so it has a \ in front:

bind r source-file ~/.tmux.conf\; display "Reloaded"

Otherwise, on startup with "tmux", this actually tries to execute "display", resulting in a "can't establish current session" error message. This can be seen in the man page of tmux, if you search for "display-"

bind-key R source-file ~/.tmux.conf \; \
               display-message "source-file done"

I have 2 questions:

What does the :.- mean? This part seems to have no effect -

unbind o
bind o select-pane -t :.-

Also, I don't understand what this quick window command is for:

bind C-q command-prompt -I "htop" -p "Quick window command: " "new-window '%%'"

Overall, thanks for sharing this config.

The mouse configs are old.
Just use set-option -g mouse on

iTunes track didn't work.
Changed #(itunesartist) - #(itunestrack) in line 57 to #(./itunesartist) - #(./itunestrack)
Added this scripts to System Preferences > security & privacy > privacy > Accessibility
Added x rights to script: chmod +x itunesartist and chmod +x itunestrack

Updated itunesartist

#!/usr/bin/osascript
on run
	set info to ""
	tell application "System Events"
		set num to count (every process whose name is "Music")
	end tell
	if num > 0 then
		tell application "Music"
			if player state is playing then
				set info to artist of current track
			end if
		end tell
	end if
	return info
end run

Updated itunestrack

#!/usr/bin/osascript
on run
	set info to ""
	tell application "System Events"
		set num to count (every process whose name is "Music")
	end tell
	if num > 0 then
		tell application "Music"
			if player state is playing then
				set info to name of current track
			else
				set info to "Not Playing."
			end if
		end tell
	end if
	return info
end run

iTunes track didn't work.
Changed #(itunesartist) - #(itunestrack) in line 57 to #(./itunesartist) - #(./itunestrack)
Added this scripts to System Preferences > security & privacy > privacy > Accessibility
Added x rights to script: chmod +x itunesartist and chmod +x itunestrack

I saved my scripts inside /usr/local/bin, and added the scripts to accessibility and added x rights to the scripts, but didn't have to change line 57 from #(itunesartist) - #(itunestrack) to #(./itunesartist) - #(./itunestrack)

This config is very old with the current tmux version, ex: unbind-key
