@ -127,7 +127,7 @@ The following input modes are available:
By default, this mode uses Ctrl+Shift+U (`LCTL(LSFT(KC_U))`) to start Unicode input, but this can be changed by defining [`UNICODE_KEY_LNX`](#input-key-configuration) with a different keycode. This might be required for IBus versions ≥1.5.15, where Ctrl+Shift+U behavior is consolidated into Ctrl+Shift+E.
Users who wish support in non-GTK apps without IBus may need to resort to a more indirect method, such as creating a custom keyboard layout ([more on this method](#custom-linux-layout)).
* **`UC_WIN`**: _(not recommended)_ Windows built-in hex numpad Unicode input. Supports code points up to `0xFFFF`.
To enable, create a registry key under `HKEY_CURRENT_USER\Control Panel\Input Method` of type `REG_SZ` called `EnableHexNumpad` and set its value to `1`. This can be done from the Command Prompt by running `reg add "HKCU\Control Panel\Input Method" -v EnableHexNumpad -t REG_SZ -d 1` with administrator privileges. Reboot afterwards.

|`UNICODE_MODE_WIN` |`UC_M_WI`|`UC_WIN` |Switch to Windows input |
|`UNICODE_MODE_BSD` |`UC_M_BS`|`UC_BSD` |Switch to BSD input _(not implemented)_ |
|`UNICODE_MODE_WINC` |`UC_M_WC`|`UC_WINC` |Switch to Windows input using WinCompose |
|`UNICODE_MODE_EMACS` |`UC_M_EM`|`UC_EMACS` |Switch to emacs (`C-x-8 RET`) |
You can also switch the input mode by calling `set_unicode_input_mode(x)` in your code, where _x_ is one of the above input mode constants (e.g. `UC_LNX`).
