In addition to enhanced syntax coloring, display local symbols in bold to make your code easy to read. When enabled, objects and variables defined within the current file are highlighted. Distinguish quickly local from non-local symbols.
Only symbols defined in the current file are bold. Those within the current class but not defined in the current file are not bold.
Bold is applied without knowledge of context. If foo is defined somewhere in the current file, all occurrences of fooare bold even if they refer to symbols defined elsewhere.
Bold is available only if enhanced syntax coloring is enabled. Bold symbols are colored slightly darker or lighter than their non-bold counterparts, depending on the color of your background.
There is a separate option to bold non-inherited members in member and completion listboxes.
