  14. <h2>Behavior</h2>
  15. <p>The text tool allows you to create and edit labels associated with
  16. components. Which components support labels are indicated in the 'Text
  17. Tool Behavior' section of their documentation. As of the current
  18. release, the following components in the built-in libraries support labels.</p>
  19. <center><table>
  20. <tr><td valign="top"><strong>Base library</strong></td>
  21. <td><a href="pin.html">Pin</a>
  22. <br><a href="clock.html">Clock</a>
  23. <br><a href="label.html">Label</a>

  36. </td></tr>
  37. </table></center>
  38. <p>For components that can take a label but have none assigned to it currently,
  39. you can click anywhere within the component to add a label. If there is already
  40. a label, you need to click within the label. If you click at a point where there
  41. is not currently a label to be edited, Logisim will initiate the addition of a
  42. new Label component.</p>
  43. <p>In the current version of Logisim, text editing features are
  44. still fairly primitive.
  45. Selections of a region of text within a label is impossible.
  46. There is no way to insert a line break into a label.</p>
  47. <h2>Attributes</h2>
  48. <p>The attributes for the tool are the same as for the <a
  49. href="label.html">label component</a>. These attributes have no effect
  50. when editing the label on an existing component, but they are imparted
  51. to any labels created using the text tool.</p>
  52. <p>Clicking on a component supporting the Text Tool will
  53. display that component's attributes.</p>
