Expand / Collapse All Fold Levels

Fold levels can be used to simplify the view in the Editor windows by allowing you to "fold" each major section of the code so that only the header row is visible. This way, you only see the section(s) that you are actually working in. Fold levels can be collapsed and expanded, in much the same way as the tree structures that occur in the Workspace Bar.

• • Fold levels that are collapsed are indicated by a blue plus sign (+) to the left of the line containing that section's header row.
  • Fold levels that are expanded are indicated by a red minus sign (-) to the left of the line containing that section's header row.

FIG. 160 Code Folding

To use fold levels, you must first select the Enable Code Folding option in the Editor - Display and Indentions tab of the Preferences

dialog (by default, this option is disabled).

FIG. 161 Preferences dialog - Cold Folding Enabled

• • If the Enable Code Folding option has not been enabled, these two options are unavailable.
  • Also note that the application will remember your last code folding settings when the file is closed, so they will still be in place the next you open the file.
