Variables: Predefined symbols for callback commands.
These are the predefined symbols that are used as the `COMMAND` argument of callback functions of an input method driver (see MInputDriver::callback_list). Most of them do not require extra argument nor return any value; exceptions are these: Minput_get_surrounding_text: When a callback function assigned for this command is called, the first element of MInputContext::plist has key Minteger and the value specifies which portion of the surrounding text should be retrieved. If the value is positive, it specifies the number of characters following the current cursor position. If the value is negative, the absolute value specifies the number of characters preceding the current cursor position. If the value is zero, it means that the caller just wants to know if the surrounding text is currently supported or not. If the surrounding text is currently supported, the callback function must set the key of this element to Mtext and the value to the retrieved M-text. The length of the M-text may be shorter than the requested number of characters, if the available text is not that long. The length can be zero in the worst case. Or, the length may be longer if an application thinks it is more efficient to return that length. If the surrounding text is not currently supported, the callback function should return without changing the first element of MInputContext::plist. Minput_delete_surrounding_text: When a callback function assigned for this command is called, the first element of MInputContext::plist has key Minteger and the value specifies which portion of the surrounding text should be deleted in the same way as the case of Minput_get_surrounding_text. The callback function must delete the specified text. It should not alter MInputContext::plist.
