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, the Main Menu, below the Title Bar. 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. To access or close the menu using the keyboard, use Alt + the Access Key (underlined letter on the menu) for the menu. Once this is initiated, you just press the access key for each command under the main menu. To dismiss a displayed menu, press the Esc key. You can also use the navigation keys to move from menu to menu (Left and Right Arrows) or down a menu using the Up and Down Arrows. The Control/System Buttons (located at the top right corner of a window) i. Minimize button: Click this to reduce the programs to a button on the Taskbar. ii. Restore/Maximize button: This switches the window size between full-screen size (docked window) and Half-Window (or customized) size (floating or cascade window). You can also double-click the empty space of the title bar to toggle between the options. iii. Close button: Click this to dispense with the window until the next time you open the program. If the file inside the window has not been saved, it will prompt you to save it.
You can also access any of the actions by clicking the application logo or right-clicking the empty space of the title bar and then select the action you want. Moving Windows
If a window gets in the way of what you are doing, you can move it to a different place on the screen by clicking and holding the Title bar using the Left Mouse button (only possible for floating window).
You can change a windows shape or size so that you can see more of its contents or so that you can arrange windows side-by-side manually. This is possible when the window is restored down. Place the mouse over the edge of the window so that the mouse pointer changes shape to a double-pronged arrow (either side or edge), drag inwards or outwards to reduce or enlarge the window (default Restored).
