## Exercises

  1. Develop a macro that hides all files that are different in the session group buffer.

  2. Ediff is a powerful tool. So you should really try it on some of your files now, and try to understand the quick help available in the control buffer, so you can refer to this later instead of having to find this book and look it up.

  3. Windows 95 users know that program installations can modify autoexec.bat and config.sys, littering C:\ with old copies of those two files. Now you have a tool that lets you see exactly what changes were made. Look at some of your old autoexec.* files and diff them against your autoexec.bat.
