If you are like many people, you probably rely pretty heavily on your mouse for carrying out common functions such as copying and pasting. But if you happen to find yourself working on a laptop where space is restricted and a mouse isn’t a feasible option, keyboard shortcuts can take away much of the hassle and time that typically go into using a touchpad to do the same things. Here are some of the most commonly used keyboard shortcuts for changing or editing text:

• To select text: shift + arrow left/right
• To select an entire page of text: shift + page up/page down
• To copy text: control (CTRL) + C
• To cut text: control (CTRL) + X

• To close a program: ALT + F4 or ALT + F + X
• To open the task manager: control (CTRL) + shift + escape (ESC)
