2.10 Interface Conventions

The following sections document the (fairly standard) conventions used in the FDR interface.

2.10.1 GUI conventions

These general rules apply to the FDR user interface:

• Single-click with Mouse-1 (usually the left mouse button) selects activates a menu or button, or selects an item from a list.
• Double-click with Mouse-1 invokes an action on an object.
• Mouse-3 (usually the right mouse button) invokes a pop-up menu for the object under the cursor.
• Check boxes have square indicators and can be “on” or “off.” The option is off when the box is the same as the background colour, and on when it is otherwise lit.
• Radio buttons are used in a group, and are like a collection of check boxes, except they have diamond shaped indicators and only one option from the group can be selected (or “on”) at any time.

2.10.2 Keyboard short-cuts

Keyboard input can be used for the vast majority of input to FDR. The general guidelines are:

• Clicking on an object with the mouse directs subsequent input to that object.
• Pressing the Tab key moves input to the next item; pressing Shift-Tab moves input to the previous item.
• The Enter (or Return) key invokes the item currently accepting input.
• Pressing the Alt key with a letter raises the menu identified by that letter. Items can be selected from a menu using the letter underlined in the item title. Press the Esc key to cancel a pop-up menu.
