How do I select more than one cell when editing in Grid 3?

When copying or deleting, you may want to select multiple cells to copy or delete in one go. You can do this by:  

1. Open your chosen grid, browse to the three lines (top left corner) and select Edit grids.

2. Press in the gaps between the cells and drag the blue box over the cells you want to select.

You can then edit or remove all the highlighted cells.

Note: if you have a keyboard connected, you can also use the press and hold the CTRL key and select cells one at a time. This will allow you to select cells that are not next to each other.
