What is the file extension for batch files?

The correct answer is C, Shift + Enter. A manual line break, also called a soft return, moves the text to the next line while keeping it inside the same paragraph, so the spacing before and after the paragraph and the list numbering are not disturbed. It is the right way to break an address or a line of verse. Option A is wrong because Ctrl + Enter inserts a page break and throws the text on to a new page, which is a much bigger jump than a line break. Option B is wrong because Alt + Enter has no line break function in MS Word, although in MS Excel it does start a new line inside a cell, which is where the confusion comes from. Option D is wrong because Space + Enter is not a recognised key combination at all.

The correct answer is C, the first statement is true and the second false. When a new document is created in MS Word, the program offers a blank document as well as a gallery of templates for letters, resumes and reports, so statement one is correct. Statement two is wrong because Shift + End selects the text from the cursor to the end of the current line; the shortcut that takes the cursor to the end of the whole document is Ctrl + End. Option A is wrong because it denies the true statement about templates. Option B is wrong because it accepts the incorrect shortcut. Option D reverses both judgements and is therefore wrong twice over. In statement based questions of this kind, test each statement separately and only then look at the options.

The correct answer is B, Ctrl + Z. This combination reverses the last action, whether it was typing, deleting, formatting or moving, and pressing it again walks further back through the list of recent actions. Option A is wrong because Ctrl + U applies underline to the selected text in a word processor. Option C is wrong because Ctrl + Y does the opposite of undo: it redoes the action that was just undone, and the pair Ctrl + Z and Ctrl + Y is usually asked together. Option D is wrong because Ctrl + X cuts the selection and places it on the clipboard, from where Ctrl + V pastes it. The four combinations Ctrl + C, Ctrl + X, Ctrl + V and Ctrl + Z form the core of every computer awareness paper and should be answered without a moment of thought.

The correct answer is B, F2. Selecting a file or folder in Windows and pressing F2 makes its name editable at once, without going through the right click menu. The same key has a second well known use: in MS Excel it puts the active cell into edit mode so that its contents can be changed in the cell itself. Option A is wrong because F1 opens the help window of whichever program is running. Option C is wrong because F5 refreshes a window or reloads a web page, and in MS PowerPoint it starts the slide show from the first slide. Option D is wrong because F7 runs the spelling and grammar check in MS Word. The function keys are pure memory work, and F1, F2, F5, F7 and F12 are the five that appear most often.

The correct answer is C, .pptx. From the 2007 version onwards, MS Office moved to an XML based format in which every main program received an extension ending in the letter x, and a PowerPoint presentation became .pptx, the older format being .ppt. Option A is wrong because .docx belongs to an MS Word document. Option B is wrong because .xlsx belongs to an MS Excel workbook, the older form of which is .xls. Option D is wrong because there is no extension .mdbx; the old Microsoft Access database used .mdb and the newer one uses .accdb. A quick way to hold this set together is to remember the three pairs .doc and .docx, .xls and .xlsx, .ppt and .pptx, which cover most of the questions asked from Office extensions.
