I am been editing clips by cutting them but I wonder is there a way to move the clip to 0:00 easily. The most common method that I use is dragging the clip using a mouse, so I wonder is there an easier method

Right-click in the free space to the left of the clip and select: Remove Space.
This way you could simply move the clip to the beginning.

But remember, you can only move a clip to where there is enough space. If there is not enough free (temporal or time) space between other clips (or a clip and the beginning) for the clip you want to move, it won't work. There must always be enough space in the timeline for the clip you want to insert or move there.

I've assigned CTRL-NUM-0 for "Remove Space" because I need this so often.

Other possible option.
Rightclick and edit the timeline. There you can also fill in start position (next to duration and such).

Sorry for not responding, appearantly the post is not subscribe so I did not receive the notifications. Anyway thanks for the answer.
