What's New

CrossStudio

• Source code editor now has code completion capability.
• Source Navigator has a new core that is precise and can run multiple indexing threads in parallel.
• Find References (Alt+R or Ctrl+Alt+F) quickly finds references to a symbol or preprocessor definition.

• Search Includes (Ctrl+Shift+M) will open include files referenced in the focused source file.
• Project Explorer has a Filter Project (Ctrl+;) capability to show matching filenames.
• Project Explorer has accelerators for Collapse to Projects (Ctrl+P, J), Collapse to Folders (Ctrl+P, F), Collapse to Solutions (Ctrl+P, S), Collapse All (Ctrl+P, -), and Expand All (Ctrl+P, =).
