If you want to quickly select (highlight) all of the contiguous (continuous) data in your spreadsheet (such as a table of information), follow these steps:
- Click anywhere within the contiguous data
- Press CTRL+A
If there are rows or columns within your data that are completely blank, the highlighted selection will stop at those "borders."
If you want to select the entire spreadsheet, including any blank rows or columns, press CTRL+A+A (in other words, press CTRL+A, then while continuing to hold down CTRL, press "A" again).
Alternatively, you can click on the button in the top left corner...
