Ctrl+F9 is a keyboard shortcut in Microsoft Excel that minimizes or restores the current workbook window. Option A describes Alt+= (AutoSum), Option B refers to Ctrl+9 (hide rows), and Option D refers to Ctrl+F6 or Ctrl+Tab (switch to next window).

Ctrl+Shift+& applies an outside border (outline border) to the selected cells in Excel. Option A refers to Ctrl+5 (strikethrough), Option B is Ctrl+Shift+! (comma format), and Option C is Ctrl+0 (hide columns). The ampersand (&) key shares the 7 key, making this the border shortcut.

Shift+F2 edits or inserts a comment on the active cell in Excel. Option A is Shift+F4 (Find Next), Option C is F2 (edit cell), and Option D refers to maximizing/restoring with arrow keys. The Shift modifier changes F2 from editing cell contents to editing the cell comment.
