<h1>Miscellaneous Panels</h1>

<h2><a name="mouse-indicator">Mouse Function Indicator</a></h2>

<blockquote>
  <img src="images/mouse-function-indicator.gif" alt="[Mouse Function Indicator]">
</blockquote>
<p>
Mouse Function Indicator shows which functions are assigned
to each mouse button.
<p>
Although the function of each mouse button changes
depending on the state (selected mode, position of the mouse cursor,
state of SHIFT key or CONTROL key, etc) at the time,
the mouse function indicator shows the current function at all times.
<p>
If the <a href="drawing-mode.html#text">TEXT</a> mode is selected
and it is ready to enter text from keyboard,
the mouse function indicator shows that as a keyboard icon.
<p>
See also <a href="#balloons">Balloons Button</a>.

<h2><a name="ruler">Rulers</a></h2>

<blockquote>
  <img src="images/ruler.gif" alt="[Rulers]">
</blockquote>
<p>
The rulers are placed at the top and right
(left, if the <a href="drawing-mode.html">drawing mode panel</a> is <i>right</i>)
of the canvas, and the scale selected by
<a href="#unit-box">UNIT Box</a> is displayed on them (i.e. inches or cm).
Normally, triangular markers which show the mouse cursor position
are also displayed on the rulers.
The rulers may also be used to scroll the canvas.
<p>
To scroll the canvas, press mouse button 2 (`Drag') on the ruler
and move cursor left/right or up/down;
the ruler will be moved following the cursor,
and the contents of canvas will be moved when mouse button is released.
If the SHIFT key was pressed during this operation,
the canvas will scroll five times further than the mouse movement.
<p>
Clicking on the ruler with mouse button 1 (`Pan Left' or `Pan Up')
or mouse button 3 (`Pan Right' or `Pan Down')
will scroll the canvas by 1/2 inch (1cm, if unit is cm).
The arrow keys have the same effect, too.
If the SHIFT key was pressed during those operations,
amount of scroll will be five times further.
<p>
The canvas view will be moved to the origin
if mouse button 1 (`Pan to Origin') is clicked
on the <a href="#unit-box">UNIT Box</a>,
or mouse button 2 (`Pan to Origin') is clicked
on the canvas while the CONTROL key is down.


<h2><a name="unit-box">UNIT Box</a></h2>

<blockquote>
  <img src="images/unit-box.gif" alt="[Unit Box]">
</blockquote>
<p>
The UNIT Box is placed where the top and side rulers meet.
The units of the ruler (<i>in</i> or <i>cm</i>) and the scale
of the drawing (e.g. 1cm=3km) will be displayed here.

<h3><a name="set-unit">Set Units</a></h3>

Clicking on the UNIT Box with mouse button 3 (`Set Units/Scale')
will pop up a panel to set the units.
