Typing ;; C-h m while in Ultra-TeX-mode will display information on the ;; mode. ;; ;; Main features: ;; 1. Completion of control sequences. ;; Typing a backslash (\) starts lightning completion (see light.el) of ;; control sequences. The ultex-tree-file is the file of permanent ;; control sequences to complete on. Also, when you find a TeX file, ;; control sequences defined in that file are added to the list of things to ;; complete on. These sequences are not added to the permanent file, ;; however. To add a control sequence to the permanent file, use C-c C-n ;; (M-x ultex-new-cs). You can also edit the ultex-tree-file directly. ;; The permanent completion list may have sequences which do not begin ;; with a \. To complete on any sequence, including those, type C-\. ;; 2. Greek keyboards. ;; Since there are many symbols which have TeX control sequence names, ;; it is undesirable to clutter up the completion list with these. ;; Instead, several Greek Keyboards are provided in Ultra TeX mode. ;; The key ` acts as a "Greek shift" key. Typing `a will insert ;; "\alpha" in the buffer (assuming you do not change the default ;; greek key bindings). There are Greek, Shift Greek, Control ^Greek, ;; Meta Greek, Meta Shift Greek, and Meta Control Greek keyboards. You ;; can add or change a greek key by typing C-c C-g in ultra-tex-mode. ;; You can display the current greek key bindings by typing `\, `|, `C-\, ;; `M-\, `M-|, and `M-C-\. ;; The greek bindings are stored in the file ultex-greek-keys-file. ;; 3. Fonts. ;; Typing ESC B will insert "\textbf{}" or "\mathbf{}" (whichever is ;; appropriate, depending on the location of the point) and leave point ;; just inside the group. Similarly, ESC A,C,E,F,I,M,R,S,T,X,Z make ;; cAligraphic, smallCaps, Emphasis, sans-seriF, Italic, Math-italic, ;; Roman, Slant, Typewriter, teXt and uZer's-math (defined as \zz) fonts. ;; 4. Smart Return Key ;; The RETURN key moves point forward by some appropriate amount. Often ;; this means moving outside of a close bracket, or over a whole word. ;; Also, RET can remove some extraneous matter. For instance, if the ;; text looks like "[]" and the cursor is between the two brackets, ;; hitting RET deletes the pair (and similarly if the cursor is between ;; the braces in "\label{}"). This way, one can use lightning ;; completion to insert a command with lots of optional arguments, and ;; one only has to hit RET to get rid of each one. ;; To insert a newline, use ESC RET. LFD ends a paragraph when that makes ;; sense, and checks the paragraph to see if parentheses, etc. are properly ;; matched. ;; 5. Smart Dollar Signs. ;; Typing $ produces two dollar signs and puts the point in between them. ;; Typing $$ makes a displayed equation. Repeated $ cycles among the ;; following (here, @=point) ;; $$ ;; @ ;; $$ ;; ;; \[ ;; @ ;; \] ;; ;; \begin{equation}\label{@} ;; ;; \end{equation} ;; ;; \begin{equation*} ;; @ ;; \end{equation*} ;; ;; etc. ;; You get the same behavior whether there is text between the ;; starting and ending delimiters: ;; \[ ;; x=y ;; \] ;; becomes ;; \begin{equation}\label{} ;; x=y ;; \end{equation} ;; ;; 6. Miscellaneous. ;; C-c C-s inserts a basic LaTeX outline from file ;; ultex-latex-skel-file, then runs ultex-skel-hook. ;; ;; { makes a brace pair and leaves point inside. ;; ;; " makes `` or ''. ;; ;; ... makes \dots. ;; ;; ^ and _ include a brace pair. ;; ;; TAB in array environments inserts &. ;; ;; \\ will insert a newline and make new \item when that is ;; appropriate, otherwise, just inserts \\ and a newline. ;; Installation: ;; Make sure you have the files light.el, ultex.el, textree.el, and ;; greek.el. You might also want skeleton.tex.

Fixed another bug in ;; ultex-grab-commands, ultex-grab-labels. Added ;; \DeclareMathSymbol to ultex-grab-commands. Fixed bug in ;; ultex-grab-next that prevented it from finding \newcommand ;; (etc.) right at the start of a buffer. Made ;; ultex-tab-resume resume completion better. ;; 0.34 (23-Mar-1998) Fixed bug in ultex-grab-commands, ultex-grab-labels. ;; 0.33 (31-Oct-1997) Changed behavior of $ after \. ;; 0.32 (02-Sep-1997) Version number increased to keep up with light.el ;; 0.31 (01-Aug-1997) Bug fix: in ultex-grab-bibs, got error if the ;; buffer was not associated to a file. ;; 0.30 (30-Jul-1997) Changed version number when distribution was ;; reorganized. ;; 0.26 (23-Jul-1997) Fixed a problem with ultex-make-ref-from-label. ;; 0.25 (27-Feb-1997) The keymap stuff was rewritten a bit, changing ;; the way greek keys are handled (internally--not from the ;; point of the view of the user). ;; New variable: ultex-dont-use-completion. Set this to ;; be non-nil if you don't want to use lightning ;; completion. (This replaces the function ;; ultex-dont-use-completion.) ;; New variables: ultex-match-braces, ;; ultex-match-brackets, ultex-match-parens. If these are ;; non-nil, then hitting `{' (or `[' or `(') inserts a ;; matched pair of the delimiters, with the cursor in ;; between. ;; 0.24 (14-Feb-1997) Replaced ultex-current-alist with ;; ultex-current-commands, ultex-current-labels, ;; ultex-current-bibs, so one can rescan for only certain ;; kinds of commands, rather than rescan for everything. ;; Lots of other things had to be changed a little to ;; reflect this. ;; New variable: ultex-rescan-after-new-label. When ;; non-nil, then rescan the buffer for labels after each new ;; label is entered. ;; New function: ultex-dont-use-completion. Put this in ;; your ultra-tex-mode-hook if you don't want to use ;; lightning completion. ;; 0.23 (16-Jan-1997) biggest change: the dollar sign. Now hitting $ ;; while in math mode changes the starting and ending ;; strings of math mode--see examples above. ;; screwed around with ultex-grab-defs, etc., in an ;; attempt to make the code a little less unpleasant. ;; changed ultex-math-mode so that it would ignore \\[0.5in] ;; and things like that, and also so that it doesn't beep ;; when you're entering arguments to \newcommand. ;; added lightning completion on TeX commands to ;; ultex-delete-csname. ;; changed values of paragraph-ignore-fill-prefix and ;; adaptive-fill-mode in order to make comments and ;; auto-fill-mode interact with each other better. Also ;; changed value of comment-start-skip. ;; 0.2 (28-Oct-1996) started numbering the versions ;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; (require 'light) (require 'ultex-cus) ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; entry point and other main functions. ;; (defun ultra-tex-mode nil "Major mode for editing TeX documents. \\\\[ultex-fast-cs] starts lightning completion of control sequences.
