* Highlight: One line in the package list will be highlighted. It indicates
which package(s) will be affected by presses of `+', `-' and `_'.
* The dividing line in the middle of the screen shows a brief explanation of
the status of the currently-highlighted package, or a description of which
group is highlighted if a group line is. If you don't understand the
meaning of some of the status characters displayed, go to the relevant
package and look at this divider line, or use the `v' key for a verbose
display (press `v' again to go back to the terse display).
* The bottom of the screen shows more information about the
currently-highlighted package (if there is only one).
It can show an extended description of the package, the internal package
control details (either for the installed or available version of the
package), or information about conflicts and dependencies involving the
current package (in conflict/dependency resolution sublists).
Use the `i' key to cycle through the displays, and `I' to hide the
information display or expand it to use almost all of the screen.
