In all WinBase windows, there is a horizontal menubar along the top. In this menubar is a "Object" menu (see section 7.3 The "Object" Menu), and also "Subgroup" menus (see section 7.5 The SubGroup Menu(s)) for access to the sub-objects in this class.
To access the menus press and hold button-1 (left button) on the mouse while the mouse pointer is over the menu name. A smaller vertical menu window will pop up under the mouse pointer. Moving the mouse vertically while the button is still pressed will highlight the different choices in a the menu. Some of the items in the menu may have three dots `...' after them. When highlighting these menu items a cascaded menu will popup to the right of the selected menu item. The cascaded submenu may be traversed by moving the mouse pointer horizontally into the submenu, and then moving the mouse vertically as before. Again, button-1 must be pressed and held down during this operation. To select an item, release the mouse button while the mouse pointer is over the highlighted selection. To cancel the menu (to select nothing) move the mouse out of the menu and release the mouse button. Menu items which spawn submenus may not be selected. A menu may be pinned (it will stay on the screen after the mouse is released) by releasing the mouse while the pointer is on the menu name or on a submenu's name. A selection can be made from a pinned window by clicking (pressing and then releasing a button) on the desired selection. This will also cause the pinned menu to become unpinned and it will disappear.
Note: This applies specifically to the motif mode in InterViews. Open-look or other modes may be slightly different.
