Question

troy wants to select multiple cells, including adjacent and nonadjacent cells, using the mouse and keyboard in his spreadsheet. he then plans on shading them yellow for emphasis. which key does he need to press and hold while selecting the desired cells so he can shade all of the cells at one time?
a shift
b ctrl
c fn
d alt

Explanation:

In spreadsheet software, the CTRL key is used to select non-adjacent cells. Holding CTRL while clicking cells allows adding multiple separate cells to the selection, enabling simultaneous formatting (like shading) of all selected cells. SHIFT selects adjacent ranges, FN is a function modifier, and ALT has other interface-related uses, so CTRL is the correct choice.

Answer:

B. CTRL
