To select two files and all files between them, hold down _____ while clicking the two files.

Holding **Shift** while clicking two files selects both endpoints and the files between them. By contrast, holding **Ctrl** while clicking allows selection of multiple individual files, and `Ctrl+A` selects all files in the current context. These methods let a user apply one operation to a group rather than repeating it for each file. **Key takeaway:** Use Shift-click for a continuous range and Ctrl-click for individually chosen items.\n\n**Glossary:**\n- **Shift-click**: A selection method that includes the clicked endpoints and items between them.\n- **Ctrl-click**: A selection method for selecting multiple individual items.
