Did you pre-press Caps Lock or press Shift with the CTRL+A shortcut?

• Ctrl+A is used to select all cells in a worksheet or a range of cells.
• You can use other shortcuts to select different parts of a worksheet, such as:
  • Ctrl+Shift+End to select from the active cell to the last used cell on the sheet (lower right corner).
  • Ctrl+Space to select the entire column.
  • Shift+Space to select the entire row.
• You can also use VBA code to select all cells or a specific range of cells using ActiveSheet.UsedRange or Range(“A1:C3”) respectively.

One possible reason why Ctrl+A is not selecting all words in a cell is that it is assigned to a different command. To check this, you can follow these steps:

1. Go to File > Options > Customize Ribbon
2. Click on the Customize… button next to Keyboard shortcuts
3. Place the selection in the Press new shortcut key control and press Ctrl+A
4. See what it is currently assigned to. It should be to EditSelectAll.

If it is not assigned to EditSelectAll, you can change it by selecting EditSelectAll from the Commands list and clicking Assign.

I hope this helps you.
