This entry on the Tool Options dialog has three tabs.
The Syntax Color tab is shown only when the Code Editor is open.
The options you select apply only to you.
Editor tab
Window Settings group:
• Vertical scrollbar check box - specifies whether the vertical scrollbar is shown in the Code Editor.
• Horizontal scrollbar check box - specifies whether the horizontal scrollbar is shown in the Code Editor.
• Line number check box - specifies whether line numbers are shown to the left of the code in the Code Editor.
• View whitespaces check box - specifies whether whitespace is shown for tabs and spaces in the Code Editor.
• Collapsible nodes check box - specifies whether nodes are collapsible in the code. When enabled, nodes can be collapsed by clicking the collapse symbol and expanded by clicking the expand symbol.
How collapsible nodes are identified can vary with different languages. For example, for C++, collapsible nodes are identified through braces, that is, { and } characters.
• Auto indentation check box - specifies whether a new line is indented to the position of the preceding line in the Code Editor. When selected, a new line (created by pressing the Enter key) is indented to the indent of the preceding line. When cleared, a new line is not indented.
• Virtual space check box - specifies whether the virtual space feature is enabled. When selected, you can click to the right of code, and when you type text the Code Editor will add spaces to extend the line to the position you clicked. Note that when selected, you cannot navigate from one line to another through the left and right direction keys.
• Syntax colorization check box - specifies whether code syntax is shown colored as defined on the Syntax Color tab. Note that the Syntax Color tab is shown only when the Code Editor is open.
