Visual Editing Guides in Text View |
Text View provides functions to facilitate the editing of large sections of text: line numbering, bookmarks, source folding, and indentation guides. Each of these functions can be enabled or disabled by clicking its respective icon in the toolbar.
Enables/disables line numbering across all open documents
Enables/disables the source folding margin for all open documents
Enables/disables the bookmark margin.
Inserts/removes bookmarks.
Enables/disables indentation guides.
The graphic below shows these features:

Note the following features in the graphic above:
| • | Line numbering has been enabled |
| • | Source folding has been enabled. The plus sign indicates a collapsed element; the minus sign indicates an expanded element. When an element is collapsed, the line-numbering is correspondingly collapsed (see the collapsing at Lines 14 and 24). When source folding is disabled, any collapsed element is automatically expanded. |
| • | The Bookmarks Margin has been enabled. A bookmark has been created for Line 11. |
| • | Indentation guides have been enabled. These guides are vertical dotted lines that are helpful in determining where an element starts and ends (see Lines 46 and 47). |
