Cursor Command Modes

A cursor command mode is a controlled protocol for mouse and keyboard entry. In a command mode, you are limited in the types of user interface actions that can be taken. Most or all of your input is directed toward the particular command that is active. In the Image Windows, several command modes are operated from the column of buttons on the left end of the Image Bar. There are two types of cursor used in Mira Image Windows: the mouse pointer and the Image Cursor.

The Mouse Pointer refers to the pointer of the Windows interface. When moved inside an Image Window, it takes on a shape that is dependent upon the particular mode.
The Image Cursor is an adjustable crosshair or rectangle that is connected with the displayed image and cannot move outside its bounds.

When a cursor mode is activated, mouse clicks are tied to a specific type of action. For example, in Magnify Mode, clicking the mouse on the image magnifies the image at that point. When no command mode is active, the Image Window is in "Roam Mode" in which the mouse cursor can roam around the image and no specific command will be executed if you click on the image.

Tip	To exit any command mode and return to Roam Mode, use the Ctrl+A image window accelerator or click on the Image Bar.
