I filmed something and I want to delete the clip...is no possible from thumbnail menu

It is possible to delete clips on both the FS5 and FS7.
While looking at the thumbnail view, press the menu button and you'll find it.

thank you Doug,yes I saw..unfortunately you do not see why clip delete..like a Canon C100 :-) a very big problem from FS5..you can not correct the white balance..I was in a room with more green..white balance made FS5 It is corrected by adding purple I could not do that..on Sony A7S ..it's simple, right click and ready I hope sony solve this problem I say that is very important ..PLEASE SONY
