GNU Info (emacs)Fill CommandsExplicit Fill Commands ---------------------- `M-q' Fill current paragraph (`fill-paragraph'). `C-x f' Set the fill column (`set-fill-column'). `M-x fill-region' Fill each paragraph in the region (`fill-region'). `M-x fill-region-as-paragraph' Fill the region, considering it as one paragraph. `M-s' Center a line. To refill a paragraph, use the command `M-q' (`fill-paragraph'). This operates on the paragraph that point is inside, or the one after point if point is between paragraphs. Refilling works by removing all the line-breaks, then inserting new ones where necessary. To refill many paragraphs, use `M-x fill-region', which divides the region into paragraphs and fills each of them. `M-q' and `fill-region' use the same criteria as `M-h' for finding paragraph boundaries (Note: Paragraphs). For more control, you can use `M-x fill-region-as-paragraph', which refills everything between point and mark. This command deletes any blank lines within the region, so separate blocks of text end up combined into one block. A numeric argument to `M-q' causes it to "justify" the text as well as filling it. This means that extra spaces are inserted to make the right margin line up exactly at the fill column. To remove the extra spaces, use `M-q' with no argument. (Likewise for `fill-region'.) Another way to control justification, and choose other styles of filling, is with the `justification' text property; see Note: Format Justification. The command `M-s' (`center-line') centers the current line within the current fill column. With an argument N, it centers N lines individually and moves past them. The maximum line width for filling is in the variable `fill-column'. Altering the value of `fill-column' makes it local to the current buffer; until that time, the default value is in effect. The default is initially 70. Note: Locals. The easiest way to set `fill-column' is to use the command `C-x f' (`set-fill-column'). With a numeric argument, it uses that as the new fill column. With just `C-u' as argument, it sets `fill-column' to the current horizontal position of point. Emacs commands normally consider a period followed by two spaces or by a newline as the end of a sentence; a period followed by just one space indicates an abbreviation and not the end of a sentence. To preserve the distinction between these two ways of using a period, the fill commands do not break a line after a period followed by just one space. If the variable `sentence-end-double-space' is `nil', the fill commands expect and leave just one space at the end of a sentence. Ordinarily this variable is `t', so the fill commands insist on two spaces for the end of a sentence, as explained above. Note: Sentences. If the variable `colon-double-space' is non-`nil', the fill commands put two spaces after a colon. Some languages do not use period to indicate end of sentence. For example, a sentence in Thai text ends with double space but without a period. Set the variable `sentence-end-without-period' to `t' to tell the sentence commands that a period is not necessary. automatically generated by info2www version 1.2.2.9 |
