When I press the prefix-key Ctrl-b tmux doesn't give me a hint that it has been pressed.
Sometimes I can not remember whether I have already pressed it or not.
Can I set up a hint like highlight/change color or show some special symbol in the status bar to show me when I have pressed the prefix-key?
The development version of tmux has support for this, so the next release (1.8?) should also support it.
There have been two changes that can be combined to indicate in your status line whether a prefix key has been pressed:
You can include the extended “format” replacements in the values of the “status” options. These replacements were first available in tmux 1.6, but they were not previously usable in the status options.
The client_prefix format replacement was added.
You could add a (conditional) highlighted <Prefix> string before the default status-right like this:
set -g status-right ' #{?client_prefix,#[reverse]<Prefix>#[noreverse] ,}"#{=21:pane_title}" %H:%M %d-%b-%y'
There's also a Tmux plugin called tmux-prefix-highlight that does this.
It adds a new keyword, #{prefix_highlight} to use in the string that defines your tmux status bar, like so:
set -g status-right '#{prefix_highlight} | %a %Y-%m-%d %H:%M'
I created plugin for this. It indicates copy mode as well, is easily customizable and has good out-of-the-box experience.
https://github.com/dominikduda/tmux_mode_indicator
As readme says:
Plugin indicating normal/insert/prefix/copy modes.
It adds a new keyword, #{tmux_mode_indicator} to use in the string that defines your tmux status bar. Like this:
set -g status-right "#{tmux_mode_indicator}"

I'd like to be able to issue a command like this:
tmux new-window -n irc ssh -t eco /usr/bin/weechat
and have the title of the new window be "irc". Instead, as soon as weechat launches, the title changes to weechat.
I had been under the impression based on the tmux man page that if you set a window title explicitly, automatic-rename would be disabled for you:
automatic-rename
[...] This flag is automatically disabled for an individual window when a
name is specified at creation with new-window or new-session, or later
with rename-window, or with a terminal escape sequence.
But that seems to not be the case. What am I missing here? I do want automatic-rename in most cases - I just want to also be able to specify -n windowname and have it take precedence.
I use vim, and so I wanted to change a couple of tmux's default bindings. In particular I wanted to change the resizing commands so that e.g. ctrl-b ctrl-k resize the split up by one position. I entered the following into my .tmux.conf:
bind-key C-k resizep -U
and it works, except that it only allows me to resize by one unit at a time before I have to hit ctrl again. In other words, I can't hold down ctrl and press b followed by k a bunch of times (while still holding down ctrl), whereas I can hold down ctrl, press b, and then press the up arrow key a bunch of times.
Does anyone know exactly why this is, or how I might replicate my desired behavior?
You need to specify the -r parameter in your command:
bind-key -r C-k resizep -U
As explained in tmux man page:
bind-key [-cnr] [-t mode-table] key command [arguments]
(alias: bind)
Bind key key to command. By default (without -t) the primary
key bindings are modified (those normally activated with the
prefix key); in this case, if -n is specified, it is not neces‐
sary to use the prefix key, command is bound to key alone. The
-r flag indicates this key may repeat, see the repeat-time
option.
I want to use Ctrl-semicolon for tmux's prefix. But my conf doesn't work.
unbind-key C-b
set-option -g prefix C-\;
I found a similar article. But it's not for the prefix.
tmux bind semicolon
Terminal can't register a Ctrl-; keystroke. It's just not a valid character. If you look at the control characters in the below ascii table, you'll see Ctrl-; is not on the list.
I'm on OS X and when I type Ctrl - ; in the (terminal and in a "desktop" program) I get a bell sound indicating the character is not recognized or something.
As for the "favorite" prefix key: from what I saw reading other people's .tmux.conf files, Ctrl-a is the most popular choice. This makes sense because:
Ctrl-a was the default for GNU Screen, tmux predecessor
it's much easier to type than the default Ctrl-b especially when you remap caps lock to ctrl.
The downside to using Ctrl-a is that you can't use the same key in bash or vim, but that's easily solved by having the following binding in .tmux.conf:
bind-key 'C-a' send-prefix
With that, pressing the Ctrl-a twice will send the same character to the underlying program (eg bash or vim).
As others said, you can't bind to Ctrl-; because it's not a valid character.
I like that prefix because it's really easy to press when CapsLock is remapped to Ctrl.
My workaround, for Linux, was to remap Ctrl-; to Ctrl-B at the xkb level.
Xkb is the Xorg subsystem which handles keyboard layouts.
I'm using the us layout, so I modified the /usr/share/X11/xkb/symbols/us at line 42:
key <AC10> { [ semicolon, colon ] };
to
// key <AC10> { [ semicolon, colon ] };
key <AC10> {
type="BABEL_CONTROL_LEVEL3",
symbols[Group1]= [ semicolon, colon, b ]
};
This tells Xkb to generate for AC10 (the 10-th button in the C row) semicolon at level 1 (no modifiers), colon at level 2 (shift modifier) and b at level 3 (Ctrl modifier).
Level 3 in Xkb is not activated by Ctrl generally, for this reason I created a new key type, which I called BABEL_CONTROL_LEVEL3. You need to put its definition in /usr/share/X11/xkb/types/pc:
type "BABEL_CONTROL_LEVEL3" {
modifiers = Shift+Control;
map[Shift] = Level2;
map[Control] = Level3;
level_name[Level1] = "Base";
level_name[Level2] = "Shift";
level_name[Level3] = "Control";
};
You'll need to restart X or reboot.

If you want to use control-semicolon, you can try AutoHotkey.
This is my tmux & autohotkey settings.
Tmux:
set-option -g prefix 'C-\'
AutoHotkey:

after installing prezto when I press CTRL - RIGHTARROW I can see these characters
source python;5C;5C;5C;5C
Whereas emacs key bindings like ALT- f work fine.
I just want my default keybindings where I can navigate using CTRL keys.
My efforts:
Raised a issue on github + browsed other similar issues as well.
Couldnt figure out how their solution would help my case.
Tried setting zstyle ':prezto:module:editor' key-bindings '' but it did not
work.
I have also checked modeles/editor/init.zsh but the script is
too long n I dont wanna make random changes and later keep
maintaining those.
Can anyone suggest a way so that my keybindings remain "UNCHANGED" even after .zpreztorc is loaded ?
If you're using the prezto editor module, it will override your key bindings. If you have it set to emacs mode with
zstyle ':prezto:module:editor' key-bindings 'emacs'
you will need to add your key bindings to that named keymap. You can do that with
bindkey -M emacs '^[[1;5C' forward-word
bindkey -M emacs '^[[1;5D' backward-word
This will need to be run after the editor module is loaded. You can do that by adding it to the bottom of your .zshrc file. I use the vi keymap, so I need to add the key bindings to both the viins and vicmd keymaps.
for keymap in 'emacs' 'viins' 'vicmd'; do
# [Ctrl-RightArrow] - move forward one word
bindkey -M $keymap '^[[1;5C' forward-word
# [Ctrl-LeftArrow] - move backward one word
bindkey -M $keymap '^[[1;5D' backward-word
done
unset keymap
When I search in, for example, man ls while in a tmux session, the search strings don't appear highlighted - the page jumps down so that the search string is on the top line of the buffer, as expected, but it's not highlighted.
Doing the same thing in the same shell while not in a tmux session results in highlighted search strings.
I have no idea where to start looking to solve this. Any hints are appreciated.
Based on Less Colors For Man Pages by Gen2ly, here is my man page and how to do it:
Preview
This is a shell, not a web page !
How to
(optional) I'm using Tomorrow theme for Konsole/Yakuake ;
Edit your ~/.bashrc ~/.zshrc, etc. to add :
# Colored man pages: http://linuxtidbits.wordpress.com/2009/03/23/less-colors-for-man-pages/
# Less Colors for Man Pages
export LESS_TERMCAP_mb=$'\E[01;31m' # begin blinking
export LESS_TERMCAP_md=$'\E[01;38;5;74m' # begin bold
export LESS_TERMCAP_me=$'\E[0m' # end mode
export LESS_TERMCAP_se=$'\E[0m' # end standout-mode
export LESS_TERMCAP_so=$'\E[38;5;016m\E[48;5;220m' # begin standout-mode - info box
export LESS_TERMCAP_ue=$'\E[0m' # end underline
export LESS_TERMCAP_us=$'\E[04;38;5;146m' # begin underline
Reload your config and try a man page search :
. ~/.bashrc && man ls
Fixed it. The problem is to do with the way that the screen $TERM handles italics. From the tmux FAQ:
vim displays reverse video instead of italics, while less displays italics
(or just regular text) instead of reverse. What's wrong?
This matches my problem exactly. The $PAGER used by man is less by default - basically, man uses less to show the contents of the manual pages. In my case, less wasn't highlighting text, just showing regular text.
The reason for this happening:
Screen's terminfo description lacks italics mode and has standout mode in its
place, but using the same escape sequence that urxvt uses for italics. This
means applications (like vim) looking for italics will not find it and might
turn to reverse in its place, while applications (like less) asking for
standout will end up with italics instead of reverse.
The solution is to make a new terminfo file for tmux, which lets it know that italics are supported. The solution's outlined in the (at time of writing) very, very bottom of the tmux FAQ.
After creating the new terminfo file, in tmux: C-b :source-file /absolute/path/to/.tmux.conf (from this SuperUser question) - this should make tmux reload the .tmux.conf file. However, this didn't work for me, and the changes only applied after restarting the tmux server (close all tmux sessions, then re-open them).
This thread is a few years old but is still the one that comes up as the best search result, so I'm answering with what finally worked for me. This is based off of tmux FAQ.
...but the instructions aren't completely clear on when or where to substitute the -256color string. I use gnome-terminal (v 3.16.2) with tmux, and this worked for me:
$ mkdir $HOME/.terminfo/
$ screen_terminfo="screen-256color"
$ infocmp "$screen_terminfo" | sed \
-e 's/^screen[^|]*|[^,]*,/screen-256color|screen with italics support,/' \
-e 's/%?%p1%t;3%/%?%p1%t;7%/' \
-e 's/smso=[^,]*,/smso=\\E[7m,/' \
-e 's/rmso=[^,]*,/rmso=\\E[27m,/' \
-e '$s/$/ sitm=\\E[3m, ritm=\\E[23m,/' > /tmp/screen.terminfo
$ tic /tmp/screen.terminfo
And tell tmux to use it in ~/.tmux.conf:
set -g default-terminal "screen-256color"
Note: I tried it once without the -256color and since that didn't work (still seeing italics instead of highlighting), I had to delete everything under the .terminfo dir (another dir called 's') before the infocmp would work.
