Synopsis:

up [count]

Move the current frame up to a caller in the stack trace (an older frame). 0 is the most recent frame. If no count is given, move up 1. This is same as down, but moving in the opposite direction.

Examples:

up        # Set current frame to the caller of this current one
up 1      # Same as above
up -1     # Same as down
