Usually in top right corner you get three things, to minimize, maximize or close a window.
First, what do you call this trio of things? Unless I know that I cannot search for my question about them.
Second, they have dissappeared, uniformly for every software package on my PCLinuxOS system (uses KDE).
I've tried KDE control centre for hours trying to get my 'whatever they are called' back again, to no avail.
I'm a bit embarrassed to ask, as it is such a simple query, but I honestly don't know what to call them or how to get them back.
Help much appreciated.
