^previousSibling^

A simple Boolean test for whether the currently processed note has a previous sibling (N.B. not always the original's previous sibling). This is useful for export context where differing output is required when the current note is the first sibling.

This test also solves the problem of testing for siblings when when exporting agent aliases or mixed original/alias siblings.

Example:

^if(^previousSibling^)^... 

The test is analogous to testing prevSibling or firstSibling in an action code context.
