Common Terms Related to Mouse
The mouse performs several common actions:
Pointing: ‘Pointing’ means to move the mouse pointer to the required place on the computer screen.
Click: ‘Click’ means to press the left button of the mouse once and to release it quickly (tapping once). It
helps to select an object like an icon, an option, a tool button, etc. It is also known as left click in which the
left button must be pressed down once with the index finger.
Double Click: It means pressing the left button of the mouse twice in a quick repetition to start/open an
application after placing the mouse pointer on that item.
Right Click: It means to press the right button of mouse and to release it quickly. It helps to open shortcut
or context menu. Use middle finger to press the right mouse button.
Drag and Drop: ‘Drag’ means to select and move an icon, file, folder or a picture from one place to another
on the screen. In order to drag, put the mouse pointer on the desired icon on the screen, then press the
mouse button and without releasing the button move the pointer to the destination point and release the
button. The object will be ‘dropped’ or placed in the new location.
Scroll: Many applications provide scroll bar on right side of screen if the page length is more than the
monitor/screen length. Instead of using page down key or arrow keys, one can use scroll key of a mouse
to scroll up or down. If the scroll key is not available, one can click on the scroll bar on the application
screen with the left button of the mouse. Use the scroll wheel on the mouse to move the page on the
screen up or down.
Blocking Text: It is a way to select text on a computer screen for editing or formatting. To do this, click at
the beginning of the word or sentence while holding down the left mouse button. Then, drag your mouse
cursor along the text you want to select. As you drag, the text will be highlighted (usually in a different
color, like black or blue, depending on the system or application). Once you’ve highlighted the desired text,
release the left mouse button. This method allows you to easily choose specific parts of text to work with,
whether you’re editing an essay or formatting a document.
