I am using Eclipse Java IDE for Web Developers (Oxygen.3a.Release (4.7.3a)) on Ubuntu 16.04.4 and within code I am unable to delete the previous word relative to my text pointer. The command is supposed to be Ctrl + Backspace, but this doesn't work. The command Ctrl + Del does not work either.
Is this a known problem/bug? Is there a way to fix it?
