How to mosaic multiple raster datasets?

There are two options you can use to accelerate the process of adding raster images to the input rasters list to mosaic:

1. Select the first raster in the input raster of mosaic tool to add to it the raster list, then keep pressing the downwards arrow button ↓ on your keyboard to add the rest of rasters until the end.
2. Use the browse button to navigate to the folder to select all rasters from the folder, assuming that all rasters are located in the same folder. If not, then use the first option. This is the fastest I know.
