WiscChat (Psi) - Search Your Roster for a Contact
Locate a contact on your Psi roster by using the improved search feature of Psi .12 or later.
Once you have added many contacts to your chat roster in Psi, it can be time consuming to search through the list looking for a particular user. Starting with Psi version .12, it is possible to search your contact list by simply typing with any roster contact highlighted. Once you begin typing, a search box appears at the top of the roster.
Note that all contacts whose names contain (not just start with) the search term will be displayed, while all other contacts will be filtered out. This method only searches based on contact names as they are listed on your contact list, and does not search vCard details or email addresses. After the search has been completed, you can return to the full roster by pressing the Escape key, or by clicking the "X" next to the search window.
