- <h1>Poking memory</h1>
- <p>You can manipulate the contents of memory using the Poke Tool,
- but the interface for this is severely limited by space constraints:
- For more than the simplest editing, you will probably
- find <a href="hex.html">the integrated hex editor</a> far more
- convenient.</p>
- <p>Nonetheless, to view and edit values within the circuit, the
- Poke Tool has two modes of operation:
- You can edit the address displayed, and you can edit an individual
- value.</p>
- <p>To edit the address displayed, click outside the display rectangle.
- Logisim will draw a red rectangle around the top address.</p>
- <ul>
- <li><p>Typing hexadecimal digits will change the top address
- accordingly.</p></li>
- <li><p>Typing the Enter key will scroll down one line.</p></li>
- <li><p>Typing the Backspace key will scroll up one line.</p></li>
- <li><p>Typing the space bar will scroll down one page (four lines).</p></li>
- </ul>
- <p>To edit a particular value, click the value within the display
- rectangle. Logisim will draw a red rectangle around that address.
- <ul>
- <li><p>Typing hexadecimal digits will change the value at the address
- currently being edited.</p></li>
- <li><p>Typing the Enter key will move to editing the value just below it in
- the display (down one line).</p></li>
- <li><p>Typing the Backspace key will move to editing the value at the
- previous address.</p></li>
- <li><p>Typing the space bar will move to editing the value at the following
- address.</p></li>
- </ul>
- <p><strong>Next:</strong> <a href="menu.html">Pop-up menus and files</a>.</p>
