skimming option

"skimming " in the sense , we can move mouse left and right direction the way we want without pressing any single key, no - J,K,L keys and LMB ( left mouse button ) . also it helps to trim the clips fast from start and end points. also we can decide our speed ramp points just by moving mouse and many more things.using the J,K,L keys , tapping multiple times increases editing time. just by using mouse , and setting up any two customised keys , we can cut ,trim the clips the way we want...as like final cut pro.  its a good software but it needs skimming option to make edit better and faster.

"Skimming" ... is what?

You can use multiple taps of the J and L keys to speed up playback, of course. J is reverse, L is forward. Hit a second time, you increase speed. Hit again, increase even more.

K is of course "stop playback".
