I'll use the title line to store the name of the DSO and Thread and the 
help line to state that to zoom out, press -> + zoom out, and I think
that it is a good idea to use 'd' and 'D' to zoom in/out of DSOs and 't'
and 'T' to zoom in/out of DSOs.

F1 and textboxes with a short description of what can be done given for
the first time or till the user presses "Suppress these info boxes" will
be added.

Here I thought that something had to be done to avoid that accidentally
pressing ESC two times or having "Yes" as default option, trowing away
possibly a long processed session, what do others think about it?

I think that ESC + "Yes" as a default may be ok, as two keys need to be
pressed (ESC + Enter), enough warning/confirmation, I gues, right?
