Put a pane into customize mode, where options and key bindings may be browsed and modified from a list. ## Syntax ```tmux-usage tmux customize-mode [-NZ] [-F format] [-f filter] [-t target-pane] ``` ## Behavior Put a pane into customize mode, where options and key bindings may be browsed and modified from a list. Option values in the list are shown for the active pane in the current window. `-Z` zooms the pane. The following keys may be used in customize mode: | | | | ------------------------------------------------------------------- | -------------------------------------------------------------------------- | | [**Key**](https://libtmux.org/en/tmux/latest/manual/full/#Key~3) | [**Function**](https://libtmux.org/en/tmux/latest/manual/full/#Function~3) | | [`Enter`](https://libtmux.org/en/tmux/latest/manual/full/#Enter~3) | Set pane, window, session or global option value | | [`Up`](https://libtmux.org/en/tmux/latest/manual/full/#Up~3) | Select previous item | | [`Down`](https://libtmux.org/en/tmux/latest/manual/full/#Down~3) | Select next item | | [`+`](https://libtmux.org/en/tmux/latest/manual/full/#+~2) | Expand selected item | | `-` | Collapse selected item | | `M-+` | Expand all items | | `M--` | Collapse all items | | [`s`](https://libtmux.org/en/tmux/latest/manual/full/#s) | Set option value or key attribute | | [`S`](https://libtmux.org/en/tmux/latest/manual/full/#S~2) | Set global option value | | [`w`](https://libtmux.org/en/tmux/latest/manual/full/#w) | Set window option value, if option is for pane and window | | [`d`](https://libtmux.org/en/tmux/latest/manual/full/#d~2) | Set an option or key to the default | | [`D`](https://libtmux.org/en/tmux/latest/manual/full/#D~3) | Set tagged options and tagged keys to the default | | [`u`](https://libtmux.org/en/tmux/latest/manual/full/#u~2) | Unset an option (set to default value if global) or unbind a key | | [`U`](https://libtmux.org/en/tmux/latest/manual/full/#U) | Unset tagged options and unbind tagged keys | | `C-s` | Search by name | | [`n`](https://libtmux.org/en/tmux/latest/manual/full/#n~3) | Repeat last search forwards | | [`N`](https://libtmux.org/en/tmux/latest/manual/full/#N~4) | Repeat last search backwards | | [`t`](https://libtmux.org/en/tmux/latest/manual/full/#t~3) | Toggle if item is tagged | | [`T`](https://libtmux.org/en/tmux/latest/manual/full/#T~4) | Tag no items | | `C-t` | Tag all items | | [`f`](https://libtmux.org/en/tmux/latest/manual/full/#f~4) | Enter a format to filter items | | [`v`](https://libtmux.org/en/tmux/latest/manual/full/#v~4) | Toggle option information | | [`F1 or C-h`](https://libtmux.org/en/tmux/latest/manual/full/#F1~3) | Display help | | [`q`](https://libtmux.org/en/tmux/latest/manual/full/#q~3) | Exit mode | `-f` specifies an initial filter: the filter is a format - if it evaluates to zero, the item in the list is not shown, otherwise it is shown. If a filter would lead to an empty list, it is ignored. `-F` specifies the format for each item in the tree. `-N` starts without the option information. This command works only if at least one client is attached. ## C implementation Internal declarations in tmux 3.7c: * [`cmd_customize_mode_entry`](https://libtmux.org/en/tmux/latest/reference/c-variable-cmd_customize_mode_entry/) * [`cmd_choose_tree_exec`](https://libtmux.org/en/tmux/latest/reference/c-function-cmd-choose-tree-c-cmd_choose_tree_exec/) ## Use from a library Each API describes its own defaults, errors and execution model. * [Python](https://libtmux.org/en/py/latest/reference/libtmux-pane-customize_mode/) * [TypeScript](https://libtmux.org/en/ts/latest/reference/pane-pane-customizemode/) * [Go](https://libtmux.org/en/go/latest/reference/tmux-pane-customizemode/) * [C#](https://libtmux.org/en/csharp/latest/reference/libtmux-pane-entercustomizemodeasync/) tmux sources and license Syntax comes from `tmux 3.7c list-commands`.
