Working with Columns
Lists can usually be sorted (ascending/descending) by clicking on column headings
If you hover over the vertical lines with your mouse, you will notice that column widths can be adjusted as well
Searching - Using the 'magnifying glass'
Clicking the 'magnifying glass' next to a field will usually open up a separate search window on top of the page to help the user select the value
In the case of 'Site', this new window will be populated with the sites already in use by your project and allow you to add more
Accessing Help, Internal Links, and System Functions
Underlined text in blue takes the user to a particular area of the system or displays more extensive help information; mouse over will display a little more information
Underlined text in purple provides access to context sensitive help or executes the listed function. If the context sensitive help will be displayed a question mark will appear on mouse over; otherwise, test explaining where you will be going will be displayed
Hiding and unhiding sections
Section headings with either an up or down arrow next to them can be either hidden or displayed as needed
Drop downs work in a variety of fashions depending on the data being entered. As you become more familiar with the system you will get more used to them.
Some of the drop downs (e.g. Review Status) require the user to expand them using the "down arrow" and select their choice using the mouse.
Those with smaller domains (e.g. Wind) often step trough the list of available options based on the first character of the entry. Once it is highlighted, then the user can usually tab to the next field without using the mouse.
Those with larger domains (e.g. Common Name) will usually rely on a "starts with" or "contains" search to limit the domain of option to choose from and will require use of the mouse to select the chosen option
