| <h2 id="links">Hyperlinks</h2> |
| |
| <p>Hyperlinks allow to access context sensitive actions using the mouse. Hyperlinks are enabled |
| on demand by pressing a modifier key or key combination; if the hyperlink action is available at the |
| mouse position, the link is shown in the editor and can be triggered by a mouse click.</p> |
| <p>There are several hyperlink actions for the R editor including actions to navigate:</p> |
| |
| <table class="style1"> |
| <thead><tr> |
| <th>Name</th> |
| <th>Description / Action</th> |
| <th>Default Modifier(s)</th> |
| </tr></thead> |
| <tr> |
| <td>Element Declaration</td> |
| <td>Opens the declaration of an R element in Eclipse<br/> |
| (available for detected R element names), |
| like the command <a href="#opendeclaration">Open Declaration</a></td> |
| <td><kbd>Ctrl</kbd><br/></td> |
| </tr> |
| <tr> |
| <td>Local File Path</td> |
| <td>Opens the file in an editor in Eclipse<br/> |
| (available for detected path names in string)</td> |
| <td><kbd>Ctrl</kbd><br/></td> |
| </tr> |
| </table> |
| |
| <p>If more than one hyperlink actions are available for the current position, a chooser is opened |
| and the user can selected the desired target.</p> |
| |
| |
| <h4>Configuration</h4> |
| |
| <p>The different kinds of hyperlinks can be configured in the preferences |
| (<span class="uisequence">Window > Preferences</span>) at: |
| <span class="uisequence indent">General > Editors > Text Editors > Hyperlinking</span> |
| |
| Only items listed as <span class="uilabel">Available In</span> "R Source" in the table are relevant |
| for R code.</p> |
