<H3>Summary:</H3>
<BLOCKQUOTE>
The <B>tool</B> command selects or queries the mode of operation
of the mouse buttons in the layout window. Each <B>tool</B>
type has a unique set of button bindings. <P>
Without arguments, the <B>tool</B> command selects the next
tool type in round-robin fashion. With a tool type as argument,
the button bindings switch to those for the indicated tool.
With the <B>info</B> option, a summary of the mouse buttons is
given for the current tool. <P>
The mouse bindings for each of the three tools is as follows:
<UL>
<LI><I>Box Tool</I>
<DL>
<DT> <B>left</B>
<DD> Move the box so its lower-left corner is at cursor position
<DT> <B>right</B>
<DD> Resize box by moving upper-right corner to cursor position
<DT> <B>middle</B>
<DD> Paint box area with material underneath cursor
</DL>
In addition, you can move or resize the box by different corners
by pressing left or right, holding it down, moving the cursor
near a different corner and clicking the other (left or right)
button down then up without releasing the initial button.
<LI><I>Wiring Tool</I>
<DL>
<DT> <B>left</B>
<DD> Pick a wiring layer and width (same as "<B>wire type</B>")
