_Dbg_help_add next \
"**next** [*count*]

Single step an statement skipping functions. This is sometimes called
'step over' or 'step through'.

If *count* is given, stepping occurs that many times before
stopping. Otherwise *count* is one. *count* an be an arithmetic
expression.

Functions and source'd files are not traced. This is in contrast to
**step**.
