331 "Japanese input method by Roman transliteration and Kana-Kanji conversion.
332
333When you use this input method, text entry proceeds in two stages:
334Roman-Kana transliteration and Kana-Kanji conversion.  When you start
335to enter text, you are in the first stage, Roman-Kana transliteration.
336Type SPC to proceed to the next stage, Kana-Kanji conversion.
337
338:: Roman-Kana transliteration ::
339
340You can input any Hiragana character as a sequence of lower-case
341letters, Japanese punctuation characters by typing punctuation keys,
342Japanese symbols by typing `z' followed by another key.  See below for
343a list of all available sequences.  The characters you input are
344underlined.
345
346In addition, the following keys provide special effects:
347
348K	Change Hiragana to Katakana or Katakana to Hiragana.
349qq	Toggle between this input method and the input method `japanese-ascii'.
350qz	Shift to the input method `japanese-zenkaku'.
351	Typing \"qh\" will put you back to this input method.
352RET	Accept the current character sequence.
353SPC	Proceed to the next stage, Kana-Kanji conversion.
354
355The input method `japanese-ascii' is used to enter ASCII characters.
356This is almost the same as turning off the input method.  The only
357difference is that typing `qq' will put you back into the Japanese
358input method.
359
360The input method `japanese-zenkaku' is used to enter full width
361JISX0208 characters corresponding to typed ASCII characters.
362
363List of the all key sequences for Roman-Kana transliteration is shown
364at the tail.
365
366:: Kana-Kanji conversion ::
367
368You can convert the current Japanese characters (underlined) to
369Kana-Kanji mixed text.  In this stage, the converted text is divided
370into two parts, the current phrase (highlighted) and the remaining
371input (underlined).  The following commands can be used on the
372current phrase.
373
374SPC, C-n	kkc-next
375	Show the next candidate for the current phrase.
376	If successively typed `kkc-show-conversion-list-count' times,
377	conversion candidates are shown in the echo area.
378C-p		kkc-prev
379	Show the previous candidate for the current phrase.
380	If successively typed `kkc-show-conversion-list-count' times,
381	conversion candidates are shown in the echo area.
382l		kkc-show-conversion-list-or-next-group
383	Show at most 10 candidates for the current phrase in echo area.
384	If typed repeatedly, show the next 10 candidates.
385L		kkc-show-conversion-list-or-prev-group
386	Show at most 10 candidates for the current phrase in echo area.
387	If typed repeatedly, show the previous 10 candidates.
3880..9		kkc-select-from-list
389	Select a candidate corresponding to the typed number.
390H		kkc-hiragana
391	Convert the current phrase to Hiragana
392K		kkc-katakana
393	Convert the current phrase to Katakana
394C-o		kkc-longer
395	Extend the current phrase; pull in the first character of
396	the remaining input.
397C-i		kkc-shorter
398	Contract the current phrase; drop its last character
399	back into the remaining input.
400C-f		kkc-next-phrase
401	Accept the current phrase.  If there remains input, select
402	the first phrase as the current one, and show the first
403	candidate for the conversion.
404DEL, C-c	kkc-cancel
405	Cancel the conversion, shift back to the Roman-Kana
406	transliteration.
407return		kkc-terminate
408	Accept the whole conversion.
409C-SPC, C-@	kkc-first-char-only
410	Accept the first character of the current conversion,
411	delete the remaining input.
