Keyboard Shortcuts Questions and Answers

Answer: A

The shortcut for a warm boot is Ctrl + Alt + Del.

A warm boot restarts the computer without switching the power off, unlike a cold boot from power-on. On DOS and early Windows systems, pressing Ctrl + Alt + Del restarted the machine directly; in later Windows versions it opens the security screen from which a restart is chosen.

Alt + F4 closes the active window, Ctrl + Shift + Del opens a browser's clear-history dialog, and Tab + Del has no standard function.

Correct answer: num lock

With Num Lock off, the keys of the number pad act as the arrows, Home, End, Page Up and Page Down printed on them; turning it on makes them type digits instead. The question describes the state with Num Lock switched off, which is why Num Lock is the key that governs it.

Answer: D

Correct answer: Any of the above

Ctrl + Shift with an arrow key extends the selection by whole words or paragraphs, so any of the four directions highlights a block - up and down by paragraph, left and right by word.
