Main and Context-Sensitive Menus

* We have seen that a menu on the same object can be different depending on what item you click to access such a menu. Based on this, a menu that appears when you simply click an object is considered the regular menu of the object, and it is simply called the menu. Sometimes when you click or even right-click an object, a menu might not appear. On the other hand, if a menu appears when you right-click an item or an area of a window, this menu is referred to as the context-sensitive menu.

* Most
applications display a menu in their top section. On this site, such a menu will be referred to as the Main Menu. The main menu displays columns of menus, each column is represented by a word (sometimes it will be more than one word for a menu item). To use this main menu, you can click a word. This causes a list of menu items to display. There are no strict rules (only suggestions) on what items must appear under what word. The person who creates an application also decides on the menu columns, their items, and their roles.

* After clicking a menu column, if you find the item you are looking for, you can click it. If you don't see the item you are looking for and you want to check another column, you have two options. You can simply move the mouse to another menu column of your choice. You can also click the menu item you had opened, then click the new column you desire. If you still don't see what you are looking for, you can dismiss the menu.


* There are various ways you can dismiss the menu if it is opened. If you click an item in the list of the displayed column, the menu would retract and close itself. If you have opened a menu but don't want to use it anymore, you can click one of the menu items on top. You can also click anywhere other than the opened menu; this also closes the menu. We will also learn how to close the menu using the keyboard.


* If a menu appears when you right-click an item, we will call it the context-sensitive menu. When necessary, you will be directed when to use the main menu or the context-sensitive menu.
