<p class="Paragraph"><help:key-word value="alignment; fine-tuning" tag="kw67343_2" xmlns:help="http://openoffice.org/2000/help"/>For alignment, the <span class="T1">alignl, alignc</span> and <span class="T1">alignr</span> commands are especially effective, if you are</p>
<ul class="L1">
<li class="">
<p class="P2">aligning numbers and denominators, e.g. {alignl a}over{b+c};</p>
</li>
<li class="">
<p class="P2">constructing binoms or stacks, e.g. binom{2*n}{alignr k};</p>
</li>
<li class="">
<p class="P2">aligning the elements in a matrix, e.g. matrix{alignr a#b+2##c+1/3#alignl d} and</p>
</li>
<li class="">
<p class="P2">beginning a new line, e.g. a+b-c newline alignr x/y.</p>
</li>
</ul>
<p class="Paragraph"/>
<p class="Paragraph">When using the align instructions, please note that</p>
<ul class="L2">
<li class="">
<p class="P3">they should only be placed at the beginning of expressions and only occur once. Therefore you cannot enter a+alignr b, but can enter a+b alignr c;</p>
</li>
<li class="">
<p class="P3">they mutually affect each other, which means that entering {alignl{alignr a}}over{b+c} aligns a on the right.</p>
</li>
</ul>
<p class="Paragraph"/>
<p class="Paragraph">If a line or an expression begins with text, as standard it is aligned on the left. With the corresponding align commands you can of course make a different format, compare stack{a+b-c*d#a-b+c#"text"} with stack{a+b-c*d#alignl a-b+c#alignr "text"}. Text must always be surrounded by inverted commas (not typographic).</p>
<p class="Paragraph">An interesting possibility for alignment is offered with using empty groups or character strings. Place an empty character string, i.e. the inverted commas which surround any text "", before the section of formula, which you want to align on the left. The standard centralized formulas can be aligned to the left, without using the <span class="T1">Format - Alignment</span> menu for this, compare "An example" newline a+b newline ""c-d. Similarly with empty groups, compare b+b+b+b+{}"This is another example" newline a+a+a+a+a+a. Here the text, presupposing that the standard settings were not changed, is centered.</p>
<p class="Paragraph">When typing information in the command window, note that some formats require spaces for the correct structure. This is especially true when entering values (e.g. a lsup{3}) instead of placeholders.</p>
