I usually use Adobe Premiere, and it is very similar. But it's not available on linux (I don't think).

But it does basically work the same way. In Premiere, you press "V" for the selection tool, to select clips and move them around. Press "C" to cut the clips. The effects are in a tab, inside the bottom right window. You select the one you want, and drag it onto the clip. Then select the clip and go to the effect tab inside the top left window to adjust the effect. That covers the majority of editing I think...
