Keyboard shortcuts

Use CTRL for Windows and CMD for Mac OS X:

General‍

• Project Save: CMD / CTRL + S
• Undo: CMD / CTRL + Z
• Redo: CMD / CTRL + Y

Timeline

(While hovering the mouse cursor over the timeline)

• ‍Timeline Zoom: CMD / CTRL (Hold down) + Mouse Scroll 
• Multiple Clip Selection: CMD / CTRL (Hold down) + Left Click
• Horizontal Timeline Scroll: Shift + Mouse Scroll
• Ripple Split : Hold down SHIFT or  CMD + Left Mouse Button drag. This cuts multiple clips on different tracks at once and moves them in the direction of the mouse drag, creating a gap where other media can be added.
• Ripple Move : Select the clip, hold down SHIFT or CMD + left mouse button drag. This moves media files while maintaining their relative positions to each other on the timeline.
• Multi-Select Clips From Your Timeline: Click and Drag

Video Canvas

(While hovering over the canvas)

• Canvas Zoom: ‍CMD / CTRL (Hold down) + Mouse Scroll

Copy and Paste

• Copy Elements in The Timeline or Canvas: ‍CMD / CTRL + C 
• Paste Elements in The Timeline or Canvas: CMD / CTRL + V
• Cut Elements in The Timeline or Canvas: CMD / CTRL + X

Note: Pasting an element will position it on a new track at the top of the timeline where the play-head is positioned.

Cut and Delete

• Make a Cut at the Position of the Play-Head: ‍S
• Delete the Selected Clip: DEL
• Ripple Delete (deletes the clip and everything on the track moves to the left): SHIFT + DEL

Note: Some Mac OS X systems don’t recognize CMD combinations for shortcuts in the browser. If that happens, try to use Control instead.
