GSview, Evince, Foxit, and Okular are all PDF viewer applications used to read PDF documents. XeTeX is a typesetting system used to create documents, not view them - making it the odd one out. This is a software classification question.

A standard PC keyboard typically has 104 keys, which includes the standard alphanumeric keys, function keys, navigation keys, and numeric keypad. This is the industry standard for full-size keyboards, though specialized keyboards may vary.

In Microsoft Excel, pressing F11 while cells are selected creates a chart on a new chart sheet. This is a quick shortcut to visualize selected data. F8, F9, and F10 serve other functions - F8 extends selection, F9 recalculates formulas, and F10 activates the menu bar. Note: This shortcut works in most Excel versions but behavior can vary by edition.

In Excel, ALT+PAGEUP moves to the previous worksheet and ALT+PAGEDOWN moves to the next worksheet. These shortcuts allow quick navigation between multiple sheets in a workbook without using the mouse. ALT+HOME and ALT+END are not valid worksheet navigation shortcuts.

SHIFT+F11 is the Excel shortcut to insert a new worksheet immediately before the current (active) sheet. This is useful when you need to add sheets in specific positions. SHIFT+F12 has no default function, while SHIFT+HOME and SHIFT+PAGEDOWN are for cell selection, not worksheet insertion.

In Excel, CTRL+PAGEUP moves to the previous worksheet and CTRL+PAGEDOWN moves to the next worksheet. These are the standard keyboard shortcuts for navigating between tabs in an Excel workbook.

The Edit menu in virtually all GUI applications contains the Cut, Copy, and Paste commands. This is a standardized convention across operating systems (Windows, macOS, Linux) that makes interfaces consistent and intuitive. The File menu typically deals with file operations (open, save, print), while Tools contains utilities and Special is rarely a standard menu.

The Edit menu in most applications contains clipboard operations like Cut, Copy, and Paste. These are standard editing functions for manipulating text and data within documents. The File menu handles file operations, while Tools typically contains utilities and settings.

The Ctrl + Right Arrow keyboard shortcut moves the cursor one word to the right in most text editing environments across Windows and Linux systems. This is a standard navigation shortcut used in word processors, text editors, and browser text fields.

Alt + E is the standard keyboard shortcut to access the Edit menu in most Windows programs. This shortcut opens a dropdown menu with options like Cut, Copy, Paste, Find, and Replace. Alt + F opens the File menu, while Ctrl + E has different functions in various programs (often search or center alignment).

Shift + Delete (or Shift + Del) is a keyboard shortcut used to cut selected items in many Windows programs and file managers. This removes the item and places it in the clipboard for pasting elsewhere. Ctrl + Del typically deletes to the right of the cursor, Alt + Del has varied uses, and Shift + D is not a standard cut shortcut. The more common modern equivalent is Ctrl + X.

Ctrl + End is the keyboard shortcut that moves the cursor to the very end of a document in most text editors and word processors. The End key alone moves to the end of the current line, while Home moves to the beginning. Shift + Home selects text to the beginning of the line. Ctrl + Home would take you to the start of the document.

F1 is the universal help key in Windows and almost all Windows-based programs. Pressing F1 opens the help documentation, support page, or tutorial for the active application. This is a consistent convention across Windows software dating back to early versions. F2 is commonly used for renaming, F9 varies by program, and 'H' is not a help key.
