Many outdated information in the Command Summary section of the User Guide

[ncduy0303]

There are some commands that are not included in the table, and some commands currently in the table do not exist.

For example, in the Contacts Tab command table:

1. There are no find command - I think it should be filter-n and filter-c now.
2. There are no delete contacts by keywords feature in the application.

Similar issues might found in the other tables too.
