I believe it's CPU load

yeah figured its /proc/loadavg

Thank you for sharing! For those poor souls, like me, who have found themselves beating their heads against the wall (or other hard surfaces) after trying an unholy amounts [ and combinations ] of key bindings, including reserving to utilizing AutoHotKey scripts, while utilizing Windows Terminal - there is a cure!

You will have to un-bind the default actions from the key combinations in the settings.json. Example :

{ "command": { "action": "", "input": "" }, "keys": [ "alt+up" ] },
{ "command": { "action": "", "input": "" }, "keys": [ "alt+down" ] }

I am not sure if it works on all versions (in my case, version 1.2.2381.0). However, hopefully this tip will give the suffering individuals a direction at root of the cause => to check if their CLI/Terminal app is hijacking the commands.

Cheers.

mode-mouse option is no more availble in new version. Instead you can use set -g mouse on at line 13.

I love this thread. Thank you so much @premanuj, @juvenal, @spicycode 🙇‍♂️

Posted 9 years ago, and still the best game in town !

This conf. is almost perfect, it only needs the copy/paste feature, so for anybody reading this hopefully this spares you some time searching :

# Enable mouse & Copy/Paste - Requirements: xclip  
set -g mouse on 
bind -n WheelUpPane if-shell -F -t = "#{mouse_any_flag}" "send-keys -M" "if -Ft= '#{pane_in_mode}' 'send-keys -M' 'select-pane -t=; copy-mode -e; send-keys -M'"
bind -n WheelDownPane select-pane -t= \; send-keys -M
bind -n C-WheelUpPane select-pane -t= \; copy-mode -e \; send-keys -M
bind -T copy-mode-vi    C-WheelUpPane   send-keys -X halfpage-up
bind -T copy-mode-vi    C-WheelDownPane send-keys -X halfpage-down
bind -T copy-mode-emacs C-WheelUpPane   send-keys -X halfpage-up
bind -T copy-mode-emacs C-WheelDownPane send-keys -X halfpage-down
# # Use vim keybindings in copy mode
setw -g mode-keys vi
# Update default binding of `Enter` to also use copy-pipe
unbind -T copy-mode-vi Enter
bind-key -T copy-mode-vi Enter send-keys -X copy-pipe-and-cancel "xclip -selection c"
bind-key -T copy-mode-vi MouseDragEnd1Pane send-keys -X copy-pipe-and-cancel "xclip -in -selection clipboard"

I've been using tmux for about 12 years, and I was today years old that I even thought to remap selecting panes. Omg this gist is amazing.

Pretty nice, but rescaling with hjkl is suboptimal.
My proposition: use -r C-{hjkl} to allow resizing by holding ctrl and pressing b+jjj (-r indicate repeatable key )

bind-key -r C-j resize-pane -D
bind-key -r C-k resize-pane -U
bind-key -r C-h resize-pane -L
bind-key -r C-l resize-pane -R

Also adding -r to the walk bindings improves my work routine a lot. 😏

The only problem I had was that the left and right arrow keys send b and f respectively, so I did this:

# Use Alt-arrow keys without prefix key to switch panes
bind -n M-b select-pane -L
bind -n M-f select-pane -R
# ....

This might fix what @schadha17 and @IanVaughan are facing?

Very cool. How about set -g mouse-select-pane to allow selecting panes using the mouse? (1.8)

works in xterm, however not in linux consoles

Okay, thanks for the info. That was not in my focus.

Sadly I found mouse-select-pane broke my ability to copy/paste with my urxvt+Vim combo

Incompatible with tmux >= 2.9 (invalid option errors).

Hey guys, I'm back in Linux after 10+ yrs and this site...Great stuff! I need help w/TMUX, as it has really helped out w/SSD testing and debug, even though I'd only use it occasionally. But now I'm at Ricoh, and I've got 20+ dev machines to use. I need help with where to place my tmux.conf or how to set environment (Linux) so I can source (source ~/.tmux.conf) when I've done mods to that file...Please can you help??

invalid option: mode-mouse
invalid option: window-status-current-bg
invalid option: window-status-current-fg
invalid option: window-status-current-attr

Looks like some of these option names have changed over time. For example, window-status-current-bg looks like:

set-window-option -g window-status-current-style bg=default
