how to add a gap between clips in adobe premiere pro? I have a long video made of assembled cut clips and sometimes I have to insert a black gap between two clips, for instance 



Commonly I would select all the afterwards clips and zooooom out and drag and drop them a bit after as to make this gap but I would like to know if there exists a shortcut or a command to do that without to zoom out and select and drag&amp;drop because on a video with a lot of clips sometimes it is time taking..

Anything like tell adobe Premiere Pro, at this location where the cursor holds add a gap of n seconds ?
The closest thing in Premiere is the nudge keyboard shortcut. Select the clips you want to move and hit ⌘ / ctrl← or ⌘ / ctrl→ to nudge the clips one frame forward or back, and hold the shift key  ( ⌘ / ctrlshift← or ⌘ / ctrlshift→ ) to make it 5 frames. 

You can increase or decrease the amount it nudges in the preferences, so if you want ⌘ / ctrlshift← to nudge 5 seconds, open preferences then look for trim and change the Large Trim Offset amount to 125 (for 25fps, or 150 for 30fps).
