1.1     ! raeburn     1: \label{Authoring_Daxe_Toolbar}
        !             2: 
        !             3: \textbf{Daxe Toolbar}
        !             4: 
        !             5: \includegraphics[width=0.03\paperwidth]{daxetoolbar}
        !             6: 
        !             7: The toolbar provides the following buttons:
        !             8: \begin{itemize}
        !             9:   \item \textbf{Save}: saves the document and updates the preview. A shortcut for this action is 
        !            10:         \texttt{ctrl-S}. The ``Save and Edit'' button in the last LON-CAPA menu row above the Daxe menus performs the same action.
        !            11:   \item \textbf{Undo/Redo}: Daxe supports multiple undo/redo, which can also be called with 
        !            12:        \texttt{ctrl-Z} and \texttt{ctrl-Y} or \texttt{ctrl-shift-Z}.
        !            13:   \item \textbf{Cut/Copy}: These buttons can be used to copy text, elements, or even the 
        !            14:         whole document into the clipboard. The paste button is not available because of 
        !            15:         browser security constraints, but the paste action can be done easily with 
        !            16:         \texttt{ctrl-V} (web browsers want to make sure that a web site cannot read a user's clipboard 
        !            17:         without an explicit user action such as \texttt{ctrl-V}).
        !            18:   \item \textbf{Search}: displays a dialog to search and possibly replace text in the document.
        !            19:   \item \textbf{Insert image}: displays a dialog to choose an already uploaded image. 
        !            20:         If an image needs to be uploaded first, users currently have to switch to another tab 
        !            21:         to do that outside of Daxe. Daxe will automatically measure an image's dimensions 
        !            22:         and insert the width and height in the attributes. An \textit{alt} attribute should also be provided 
        !            23:         as a text alternative. The image will display directly in the document. Attributes can be modified by clicking on it.
        !            24:   \item \textbf{Insert symbol}: provides a list of symbols that can be inserted as Unicode characters.  
        !            25:         Note that, although this is less and less likely to happen, some Unicode characters might not be visible to 
        !            26:         students who do not have the right fonts.
        !            27:   \item \textbf{Insert LaTeX math}: displays a dialog to type LaTeX math, with a real-time preview. 
        !            28:         Note that the \$ signs are necessary for math to be correctly displayed in LON-CAPA.
        !            29:         \texttt{\$\$...\$\$} can be used instead of \texttt{\$...\$} to display the math as a block, centered.  
        !            30:         Alternatively, the other LaTeX math delimiters can be used: 
        !            31:         \texttt{$\backslash$(...$\backslash$)} for inline math and \texttt{$\backslash$[...$\backslash$]} for display math.  
        !            32:         LaTeX math should always be inside an \texttt{m} element, which is created automatically when the \$ button is used.
        !            33:   \item \textbf{Insert LON-CAPA math}: use this button to directly type math with the LON-CAPA math syntax in the document.  
        !            34:         A real-time preview is displayed underneath, and a click outside the text field replaces the text by the preview.  
        !            35:         There are two options for interpreting the math: \textit{symbols} and \textit{units}.  
        !            36:         With \textit{symbols}, all letters are interpreted as variables and displayed with an italic font.   
        !            37:         With \textit{units}, units such as ``m'' are recognized and displayed normally.  
        !            38:         Internally with an LON-CAPA document, the math expression you type is wrapped within \texttt{$<$lm$>$ $<$/lm$>$} tags.  
        !            39:         If a resource containing these tags is rendered on a LON-CAPA server running an older (pre-2.12) version of LON-CAPA, 
        !            40:         the tags will be ignored and the text will be displayed without any special formatting.
        !            41:   \item \textbf{Insert table}: asks for the table attributes and inserts it with 2 rows and columns.  
        !            42:         Rows and columns can be changed with the table toolbar.
        !            43:   \item \textbf{Bulleted list}: turns the current paragraph into a bulleted list, or removes the list.
        !            44:   \item \textbf{Ordered list}: turns the current paragraph into an ordered list, or removes the list.
        !            45:   \item \textbf{Rise list level}: turns a first-level list item into a simple paragraph, or moves the list indent left.
        !            46:   \item \textbf{Lower list level}: moves the list indent right.
        !            47:   \item \textbf{Add hyperlink}: adds a hyperlink over the selected text. Make sure to fill in the \textit{href} attribute 
        !            48:          with the link address, which can be relative or absolute.
        !            49:   \item \textbf{Insert anchor}: inserts an HTML anchor at the cursor position. Make sure to fill the \textit{name} attribute.
        !            50:   \item \textbf{Styles}: turns selected text into one of these styles: bold, italic, superscript, subscript.
        !            51:         A CSS stylesheet should be used for more style control. When the style is chosen before typing (with no selection), 
        !            52:         the style element's tags are visible, which makes it possible to remove empty style elements.
        !            53:   \item \textbf{Remove styles}: removes all styles from the current selection.
        !            54:   \item \textbf{Paragraph alignment}: changes the current paragraph alignment.  
        !            55:         This is only possible if the cursor is within a paragraph.
        !            56:   \item \textbf{Font type}: changes the font family for the selected text.  
        !            57:         A CSS stylesheet should be used for more style control.
        !            58:   \item \textbf{Insert section}: inserts a section with the chosen class at the cursor location.  
        !            59:         Sections are useful to structure the text with explicit roles for each block, and the icons can be useful 
        !            60:         for students to recognize each role. Once several sections of a given class are defined, 
        !            61:         it is easy to change the display for all of them at the same time using CSS.
        !            62: \end{itemize}
