minput_config_command -

int minput_config_command (MSymbol language, MSymbol name, MSymbol command, MPlist * keyseqlist)

@brief Configure the key sequence of an input method command.
The minput_config_command() function assigns a list of key
sequences @b keyseqlist to the command @b command of the input method
specified by @b language and @b name.
If @b keyseqlist is a non-empty plist, it must be a list of key
sequences, and each key sequence must be a plist of symbols.
If @b keyseqlist is an empty plist, any configuration and
customization of the command are cancelled, and default key
sequences become effective.
If @b keyseqlist is NULL, the configuration of the command is
canceled, and the original key sequences (what saved in per-user
customization file, or the default one) become effective.
In the latter two cases, @b command can be #Mnil to make all the
commands of the input method the target of the operation.
If @b name is #Mnil, this function configures the key assignment of a
global command, not that of a specific input method.
The configuration takes effect for input methods opened or
re-opened later in the current session.  In order to make the
configuration take effect for the future session, it must be saved
in a per-user customization file by the function
minput_save_config().
@par Return value:
If the operation was successful, this function returns 0,
otherwise returns -1.  The operation fails in these cases:
<ul>
<li>@b keyseqlist is not in a valid form.
<li>@b command is not available for the input method.
<li>@b language and @b name do not specify an existing input method.
</ul>
