The fastest way to add evidence to an evidence transfer is to scan a barcode. There are times when you may want to add them manually to the transfer screen though by selecting a case number. If you have a number of items to add, the process of selecting the item in the tree, right-clicking and selecting Add to Transfer might become tedious. To speed things up, you can use the Quick Add feature.
In the tree-view of evidence items, use the up and down arrows to select the item you want to add to the transfer then just press the A key (for add.) It will be added to the transfer. If any barcodes are required, you may still be prompted to scan them. The screen will remain open so you can keep moving up or down the tree pressing "A" to add the items. Click Close when you're done.
