How to adjust length of multiple clips at once?

Hello

First, is there something like the scissor tool in Cubase to slice through an audio clip with mouse or do i fkn have to mark every spot and ctrl+e?

Second, after i sliced an audio clip, if i select all the clips i wanna shorten them by dragging the end point back but when I try this it only adjusts the one clip I drag (shift etc doenst work).

How may i adjust all selected clips and pls don't tell me this is still not possible.

Thank you

In Cubase it is looking like this, you can mark all the red clips and drag the lenght.
