I could see that many Altiris Operators always open NS Console first, which is not always needed.
You can launch Resource Manager directly when you seek for particular computer using such link:
where <SERVER> stands for FQDN or IP Address of your Notification Server.
In Find Resource dialog specify as many details as you can an all computers matching your criteria will be listed:
Click on selected computer to open Resource Manager, and work with details you look for.
The same way you can search for Users, Packages or whatever else you need.
(List may vary based on which Altiris Solution you are using.)
TIP: Consider creating suitable Security Role to restrict access to specific items.
