Located between the Quick Search and Horizontal zoom bar is the cursor status buttons.
There are two options
In selection arrow mode we can select the objects within the IGB view. In pan hand mode we can grab and move the main view.
To switch between the modes of operations we have to click on the corresponding icon. This will keep the mouse operation in the mode clicked.
To toggle the mode when in view click and hold the ALT button, releasing the button will reset to the existing mouse mode.
