It displays commands just like what you see on a File menu or a Help menu. Input box - input boxes are usually small rectangles that allow you to type data into a simple interfaces like a webpage or browser window. Insufficient memory will cause errors as well. That's why software programs include minimum memory requirements. A program that needs 14MB of memory will generate errors on a computer that only has 4MB of memory if it runs at all. The same goes for disk space, monitor color depth and resolution. In these situations, problems occur the moment that a piece of software attempts to access the things (hardware, memory, space, resolution, etc. Help files are designed not only to guide the usage of a computer, they're also designed to solve problems. Inside a help file, look for a section called, "Troubleshooting" (or something similar) when you need to resolve an issue.
