When you are editing quickly (don't want to spend a lot of time) and want to use all the "beautiful things you know" for a project.. and, for example, you want to speed up some fragments, what you do is: hover over the side of the fragment and with pressed CTRL you squeeze.. well, it would be very convenient if the compressed or stretched fragment via CTRL would have an editing FX icon, and you could choose the animation type, for example "animation-timing-function: ease-in-out;" (web CSS), but now CTRL+squeeze is always a linear animation, which looks cheap for the output
