Select multiple items in Locator

Sometimes I need to open a group of related files (e.g., a source file, its header, and its .ui file). After I've entered filter text into the Locator, it would be handy to be able to select multiple files and open all of them.

For example:

1. Press ⌘K to open the Locator
2. Type in filter text
3. Do one or more of the following:
   • Hold shift and press arrow keys to select multiple items
   • Click on an item, then hold shift and click on another item to select a range
   • Click on multiple items while holding the command key to select individual items
4. Then press Return to open all the selected items
