## Description[#](https://libtmux.org/en/tmux/latest/catalog/options/terminal-features/#description)

Set terminal features for terminal types read from [terminfo(5)](). `tmux` has a set of named terminal features. Each will apply appropriate changes to the [terminfo(5)]() entry in use.

`tmux` can detect features for a few common terminals; this option can be used to easily tell tmux about features supported by terminals it cannot detect. The [`terminal-overrides`](https://libtmux.org/en/tmux/latest/catalog/options/terminal-overrides/) option allows individual [terminfo(5)]() capabilities to be set instead, `terminal-features` is intended for classes of functionality supported in a standard way but not reported by [terminfo(5)](). Care must be taken to configure this only with features the terminal actually supports.

This is an array option where each entry is a colon-separated string made up of a terminal type pattern (matched using [glob(7)]() patterns) followed by a list of terminal features. The available features are:

* 256

  Supports 256 colours with the SGR escape sequences.

* clipboard

  Allows setting the system clipboard.

* ccolour

  Allows setting the cursor colour.

* cstyle

  Allows setting the cursor style.

* extkeys

  Supports extended keys.

* focus

  Supports focus reporting.

* hyperlinks

  Supports OSC 8 hyperlinks.

* ignorefkeys

  Ignore function keys from [terminfo(5)]() and use the `tmux` internal set only.

* margins

  Supports DECSLRM margins.

* mouse

  Supports [xterm(1)]() mouse sequences.

* osc7

  Supports the OSC 7 working directory extension.

* overline

  Supports the overline SGR attribute.

* progressbar

  Supports the OSC 9;4 progress bar extension.

* rectfill

  Supports the DECFRA rectangle fill escape sequence.

* RGB

  Supports RGB colour with the SGR escape sequences.

* sixel

  Supports SIXEL graphics.

* strikethrough

  Supports the strikethrough SGR escape sequence.

* sync

  Supports synchronized updates.

* title

  Supports [xterm(1)]() title setting.

* usstyle
