well. This command ignores hidden lines and only copies visible text. This operation does not work with block selections.

•To redisplay all lines and remove the Plus and Minus bitmaps: From the main menu click View → Show All (show_all command).

Expanding/Collapsing Code Blocks

SlickEdit® Core provides a way to expand and collapse code blocks without having to clutter the gutter with Selective Display bitmaps. You can expand or collapse blocks of code by using the plusminus com- mand, whether or not Selective Display Plus or Minus bitmaps are displayed.

The plusminus command expands or collapses code blocks under the following conditions:

•If the cursor is on the first line of a code block, the block is collapsed, creating a new Selective Display region.

•If the cursor is on a line that contains a Plus (+) bitmap, the block is expanded.

•If the cursor is on a line that contains a Minus (-) bitmap, the expanded block is collapsed.

Note

•The definition of a "code block" is based on your language.

•The plusminus command is controlled by the def_plusminus_blocks configuration variable. The value is set to true (1) by default. For more information, see ConfigurationVariables.

•The plusminus command uses the same logic to identify code blocks as the command cut_code_block. See Deleting Code Blocks for more information.

Selective Display Regions

Using the Selective Display dialog, you can choose the regions you want to display or hide. Specific set- tings are provided for each region.

•Search Text - Displays lines that contain the specified search string or lines that do not contain the spe- cified string.

•Function Definitions - Displays only function headings and optionally, function heading comments.

•Preprocessor Directives - Displays a source file as if it were preprocessed according to the define val- ues specified here. If you do not remember your defines, use the Scan for Defines button.

•Multi-Level - Select this option to set multiple levels of Selective Display based on braces or indent.

•Paragraphs - Displays the first line of each paragraph. A paragraph is defined by a group of lines fol- lowed by one or more blank lines.

•Hide Selection - Select this option to hide the lines in the current selection.
