How do I select multiple records in a grid?

In many grids it is necessary to select one or more records (rows) for further analysis/action. For example selecting animals for movement between herds/lots/groups or locations, or selecting animal to include in the Holding pen

Selecting a single animal record: To select a single record in the grid, click the required record. A selected record is displayed in red.  Hence in the above grid no records are selected while in the grid below the record of animal 704 is selected:

Note that selecting one record in this way will unselect any previously selected records in the grid. 

Selecting multiple records in the grid: For selecting more than one animal record in a grid there are two options:

If there was a single animal in the block that was not required, this could be unselected by clicking while holding down the Ctrl key.

Note:  
  • Selection of records toggles between selected and unselected. Hence, including  an already selected record will change it to unselected.
