Explanation
In Excel, the keyboard shortcut CTRL + SHIFT + _ removes the outline border from the selected cells. This removes borders from the outer edge of the cell range. The shortcut to add borders is CTRL + SHIFT + &.
AI explanation
Ctrl+Shift+_ (underscore, i.e. Ctrl+Shift+Minus) is correct — it's the Excel shortcut that removes all outline/cell borders from the current selection. Ctrl+Shift+& is the complementary shortcut that ADDS an outline border around the selected cells — the opposite action, which makes it a natural but wrong distractor. Ctrl+& (without Shift) isn't a standard Excel border shortcut. Ctrl+B is bold formatting, unrelated to borders entirely.
