Hi.
I would like to know if there's a way to move a selected clip in the timezone frame by frame using the keyboard?
I looked around, but couldn't find any information about that anywhere.

Well, if you want to move the playhead through a clip frame by frame you can use the <- and -> arrow keys. To move a clip within the timeline frame by frame is not possible with the keyboard. What you could do is zoom in on the timeline until the playhead marker turns into a fat line. Now you can grab the clip and move/drag it with the mouse frame by frame. If you need to position the clip very precisely I suggest you turn on snap, move the playhead to the desired position by using the <- and -> keys and then drag the clip to the playhead position. Similarly, you could use markers to snap clips to.
