Windows 7 Pro. Audacity 2.1.0
Looked at the manual under “SCRUB.” My “TRANSPORT” menu is entirely different. There is no “SCRUB” option.
In addition, there is no “SCRUB BAR” underneath the timeline bar.
My “TRANSPORT” menu contains:
PLAY/STOP
PLAY/STOP SET CURSOR
LOOP
PAUSE
SKIP SART
SKIP END
RECORD
TIME
APPEND
OVER (is checked)
SOFTWARE
SOUND ACT RECORD
SOUND ACT LEVEL
RESCAN
The current version of Audacity is 2.3.3. It is available (free) via the Audacity website: https://www.audacityteam.org/download/
