osk is the Windows Run command that opens the On-Screen Keyboard. The other options are either incorrect or incomplete: 'ok' and 'oks' are not valid commands, 'sk' is too short and not recognized.

SHIFT + CTRL + F in Excel opens the Format Cells dialog with the Font tab active, providing access to font family, size, style, and color options. This is the standard shortcut for font formatting in Microsoft Office. The other key combinations listed are not standard font property shortcuts.

CTRL + 2 in Excel toggles bold formatting as an alternative to CTRL + B, using Excel's numbered shortcut system where 2=bold, 3=italic, 4=underline. This provides the same functionality as CTRL + B but can be more convenient with the number row. CTRL + 1 opens Format Cells instead.

SHIFT + CTRL + 7 in Excel applies borders to selected cells using the last-used border style, or removes borders if already present. This shortcut is specific to Excel and works with the bottom border by default. The 7 key was chosen for its visual similarity to a corner bracket.

SHIFT + F10 universally opens the right-click context menu in Windows applications, serving as a keyboard alternative to right-clicking or pressing the Menu key. This shortcut works across most Windows programs. SHIFT + F5 performs find or refresh, SHIFT + F1 shows help, and SHIFT + F9 varies by application.

ALT + F11 opens the Visual Basic Editor across Microsoft Office applications, providing access to VBA macros and programming environment. This shortcut works consistently in Excel, Word, PowerPoint, and Outlook. ALT + V opens View menu, CTRL + V is paste, and SHIFT + F11 inserts a worksheet.

SHIFT + CTRL + > increases font size in Microsoft Office by stepping up through available font sizes. The greater-than symbol visually represents making text larger. CTRL + + also works in some apps, while ALT + > and SHIFT + ALT + P are not standard font shortcuts.

CTRL + BACKSPACE deletes the entire word to the left of the cursor in most Windows applications, extending the normal BACKSPACE function from single characters to whole words. This is faster than repeatedly pressing BACKSPACE. DELETE removes characters to the right, and CTRL + DELETE deletes words to the right.

The keyboard shortcut Ctrl + Q is standard for exiting or quitting applications across many operating systems. While Ctrl + F4 closes the active window or tab within an application, it does not completely quit the software, making Ctrl + Q the correct option.

The correct HTML attribute value to disable autocomplete is autocomplete="Off". This prevents browsers from automatically filling form fields with previously entered data, which is important for sensitive fields like passwords or financial information.

Highlighting refers to selecting text by clicking and dragging the mouse cursor over it, which creates a shaded background effect. This is a standard feature in word processors, text editors, and most applications that handle text. Clip art refers to pre-made images, fetch means to retrieve data, and decode means to convert coded information into readable form.

To execute means to carry out or perform an instruction. In computing, after a processor fetches and decodes an instruction, it executes it - meaning it performs the actual operation specified by that instruction (such as arithmetic, logic, or data movement). Decode converts coded information, highlight emphasizes text, and select marks an item.

Minimizing a window reduces it to a button on the taskbar, removing it from the screen while keeping the application running. This is different from collapsing or diminishing, which are not standard GUI terms. The minimized window can be restored by clicking its taskbar button.
