328  "Japanese input method by Roman transliteration and Kana-Kanji conversion.
329
330 When you use this input method, text entry proceeds in two stages:
331 Roman-Kana transliteration and Kana-Kanji conversion.  When you start
332 to enter text, you are in the first stage, Roman-Kana transliteration.
333 Type SPC to proceed to the next stage, Kana-Kanji conversion.
334
335 :: Roman-Kana transliteration ::
336
337 You can input any Hiragana character as a sequence of lower-case
338 letters, Japanese punctuation characters by typing punctuation keys,
339 Japanese symbols by typing `z' followed by another key.  See below for
340 a list of all available sequences.  The characters you input are
341 underlined.
342
343 In addition, the following keys provide special effects:
344
345 K       Change Hiragana to Katakana or Katakana to Hiragana.
346 qq      Toggle between this input method and the input method `japanese-ascii'.
347 qz      Shift to the input method `japanese-zenkaku'.
348         Typing \"qh\" will put you back to this input method.
349 RET     Accept the current character sequence.
350 SPC     Proceed to the next stage, Kana-Kanji conversion.
351
352 The input method `japanese-ascii' is used to enter ASCII characters.
353 This is almost the same as turning off the input method.  The only
354 difference is that typing `qq' will put you back into the Japanese
355 input method.
356
357 The input method `japanese-zenkaku' is used to enter full width
358 JISX0208 characters corresponding to typed ASCII characters.
359
360 List of the all key sequences for Roman-Kana transliteration is shown
361 at the tail.
362
363 :: Kana-Kanji conversion ::
364
365 You can convert the current Japanese characters (underlined) to
366 Kana-Kanji mixed text.  In this stage, the converted text is divided
367 into two parts, the current phrase (highlighted) and the remaining
368 input (underlined).  The following commands can be used on the
369 current phrase.
370
371 SPC, C-n        kkc-next
372         Show the next candidate for the current phrase.
373         If successively typed `kkc-show-conversion-list-count' times,
374         conversion candidates are shown in the echo area.
375 C-p             kkc-prev
376         Show the previous candidate for the current phrase.
377         If successively typed `kkc-show-conversion-list-count' times,
378         conversion candidates are shown in the echo area.
379 l               kkc-show-conversion-list-or-next-group
380         Show at most 10 candidates for the current phrase in echo area.
381         If typed repeatedly, show the next 10 candidates.
382 L               kkc-show-conversion-list-or-prev-group
383         Show at most 10 candidates for the current phrase in echo area.
384         If typed repeatedly, show the previous 10 candidates.
385 0..9            kkc-select-from-list
386         Select a candidate corresponding to the typed number.
387 H               kkc-hiragana
388         Convert the current phrase to Hiragana
389 K               kkc-katakana
390         Convert the current phrase to Katakana
391 C-o             kkc-longer
392         Extend the current phrase; pull in the first character of
393         the remaining input.
394 C-i             kkc-shorter
395         Contract the current phrase; drop its last character
396         back into the remaining input.
397 C-f             kkc-next-phrase
398         Accept the current phrase.  If there remains input, select
399         the first phrase as the current one, and show the first
400         candidate for the conversion.
401 DEL, C-c        kkc-cancel
402         Cancel the conversion, shift back to the Roman-Kana
403         transliteration.
404 return          kkc-terminate
405         Accept the whole conversion.
406 C-SPC, C-@      kkc-first-char-only
407         Accept the first character of the current conversion,
408         delete the remaining input.
