tmux Cheat Sheet

Getting Started

`PREFIX-%`	Vertical split
`PREFIX-"`	Horizontal split
`PREFIX-o`	Switch focus between panes
`PREFIX-q`	Show pane numbers
`PREFIX-x`	Kill pane
`PREFIX-z`	Toggle active pane between zoomed and unzoomed
`PREFIX-"+"`	Break pane into window (e.g. to select text by mouse to copy)
`PREFIX-"-"`	Restore pane from window
`PREFIX-Space`	Toggle between layouts
`PREFIX-Q`	Show pane numbers When the numbers show up type the key to go to that pane
`PREFIX-{`	Move the current pane left
`PREFIX-}`	Move the current pane right
`PREFIX-"Meta+{1..5}"`	Arrange panes in one of the five preset layouts: even-horizontal, even-vertical, main-horizontal, main-vertical, or tiled. Meta key defaults to Alt. See the Standard Layouts below
`PREFIX-:` `swap-panes -s {0..n} -t {0..n}`	Swap Source and Target panes
`PREFIX-m` `PREFIX-: swap-panes`	Swap 2 panes Select the first pane then go the second pane to execute swap-panes command at the prompt

Pressing `PREFIX-[` places us in Copy mode. We can then use our movement keys to move our cursor around the screen. By default, the arrow keys work. We set our configuration file to use Vim keys for moving between windows and resizing panes so we wouldn’t have to take our hands off the home row. tmux has a vi mode for working with the buffer as well. To enable it, add this line to `.tmux.conf`: setw -g mode-keys vi With this option set, we can use `h`, `j`, `k`, and `l` to move around our buffer. To get out of Copy mode, we just press the `Enter` key. Moving around one character at a time isn’t very efficient. Since we enabled vi mode, we can also use some other visible shortcuts to move around the buffer. For example, we can use `w` to jump to the next word and `b` to jump back one word. And we can use `f`, followed by any character, to jump to that character on the same line, and `F` to jump backwards on the line.
`^`	Back to indentation
`Esc`	Clear selection
`Enter`	Copy selection
`k`	Cursor up
`j`	Cursor down
`h`	Cursor left
`l`	Cursor right
`L`	Cursor to bottom line
`M`	Cursor to middle line
`H`	Cursor to top line
`$`	End of line
`:`	Goto line
`C-d`	Half page down
`C-u`	Half page up
`C-f`	Next page
`w`	Next word
`p`	Paste buffer
`C-b`	Previous page
`b`	Previous word
`q`	Quit mode
`C-Down` `J`	Scroll down
`C-Up` `K`	Scroll up
`n`	Search again
`?`	Search backward
`/`	Search forward
`0`	Start of line
`Space`	Start selection

With most of these the number (`##`) is optional and can be omitted to resize one line. All of these can be bound to keys: `bind H resize-pane -L 5` `bind J resize-pane -D 5` `bind K resize-pane -U 5` `bind L resize-pane -R 5`
`PREFIX-: resize-pane -D ##`	Resize the current pane down by `##` lines. The `-D` is optional since by default it moves down
`PREFIX-: resize-pane -U ##`	Resize the current pane up `##` lines
`PREFIX-: resize-pane -L ##`	Resize the current pane left `##` lines
`PREFIX-: resize-pane -R ##`	Resize the current pane right `##` lines
`PREFIX-: resize-pane -y ##`	Resize the current pane to `##` lines tall
`PREFIX-: resize-pane -x ##`	Resize the current pane to `##` lines wide
