Use the Options > Save Configuration command to save the contents of the current configuration to any other configuration file. By saving configuration files, you can create several customized versions of Source Insight, with each one having different menus, keystroke assignments, screen colors, and more. The Save Configuration command can also save a specified subset of the current configuration.
Source Insight automatically saves any option changes you make, so you normally would not need to use the Save Configuration command. See: Save Configuration.
