- <h2>Behavior</h2>
- <p>The menu tool permits the user to pull up a pop-up menu for
- components that already exist. By default, right-clicking or
- control-clicking a component will bring up this pop-up menu; however, <a
- href="../../guide/opts/mouse.html">the Mouse tab</a> of the <a
- href="../../guide/opts/index.html">project options</a> allows a user to
- configure the mouse buttons to work differently.</p>
- <p>The pop-up menu for most components has two items.</p>
- <ul>
- <li>Delete: Removes the component from the circuit.
- <li>Show Attributes: Places the component's attributes into the
- window's attribute table, so that the attribute values can be viewed and
- changed.
- </ul>
- <p>For some components, however, the menu has additional items.
- Subcircuits (that is, instances of using one circuit as a "black box"
- within another) are one example of this: In addition to the above two
- items, the pop-up menu includes another item.</p>
- <ul>
- <li>View <var>XXX</var>: Changes the circuit layout being viewed and
- edited to be the subcircuit's layout instead. The values seen in the
- layout will be part of the same hierarchy as those of the supercircuit.
- (See the
- `<a href="../../guide/subcirc/debug.html">Debugging subcircuits</a>'
- section of the <em>User's Guide</em>.)
- </ul>
- <p>Other components may extend the pop-up menu also.
- In the built-in libraries of the current version of Logisim, the only
- such components are <a href="../mem/ram.html">RAM</a> and
- <a href="../mem/rom.html">ROM</a>.</p>
- <h2>Attributes</h2>
- <p>None.</p>
