Several input method engines are available for use with AOSC OS:
- Fcitx, [homepage](https://fcitx-im.org/).
- IBus, [homepage](https://github.com/ibus/ibus/wiki).
- SCIM, [homepage](https://github.com/scim-im).
# Installing an Input Method
To install an input method framework and its input method plugins, use `sudo apt install` to install one of the following packages...
- Fcitx, `fcitx-base`.
- IBus, `ibus-base`.
- SCIM, `scim-base`.
# Activating an Input Method
To activate a specific input method engine for the current user, run the following command as the **current user**:
```
$ imchooser ${IM}
```
`${IM}` here could be any of the following values:
- `fcitx`, for Fcitx.
- `ibus`, for IBus.
- `scim`, for SCIM.
Finally, re-login for the changes to take effect.
