User Manual
Properties
You can choose to view the properties of the attachment to edit it.
Name
This is where you can view and change the name of the attachment. This does not change the underlying file name.
Type
This field is normally blank but can be editable. It allows you to enter in text that can be used to group like files together. For instance in the example provided, the value "76439-W.cc_2col_pdf" is a value that is the same on other 2 Column Layout files. This lets OnSong group these files together and switch between them based on key.
Key
This is normally blank but can be populated by a content provider or manually. This is the key in which the chart is written and can be changed by tapping the row to open a key picker.
File
This will open the Import File dialog allowing you to change the file that is associated with the attachment. You can only choose a file that matches the file type of the existing file.
