Slip in the Source Window.
This is an old FCP 7 feature that was so helpful. When reviewing footage in the source window, if there is an in and out point, it would be SO HELPFUL if you could slip the in and out points to a different position in the clip without having to manually slide it over with the mouse. Many times, if it is a long clip, you have you zoom out to see the existing in and out points, then zoom in close enough to find the little handle in the middle of the in and out points, then you have to click on it when and ONLY when the little hand icon appears, then you have to drag it to the new location. If you forgot to set a marker before you started all this, then you lost the new location on the clip that you want to be your in and out. PLEASE PLEASE make a keyboard shortcut to slip in the source window!

Yes, After Effects is already with this option, so why not premiere.

Totally agree! I've wasted so much time on this exact thing.
