Camtasia Slow Down Audio

When i am trying to edit a clip, sometimes i would like to slow the playback down to like half speed so i can more easily see where i need to start or stop an edit (for example trying to cut out an "um").. How to slow down or fast forward a video in camtasia 9 before starting to look for the way to create slow motion or fast forward effects in camtasia 9 make sure that the video clip you want to edit is placed on the editor's timeline.. Is there a way to change the playback speed of a screencast recorded with camtasia for mac? alt-clicking on fast forward or rewind will speed up or slow down playback speed (as will mouse-scrolling sideways). i actually did everything with 1.5
