For FPS it's: cg_drawfps 1
For time it's: cg_drawtimer 1
Another one I find useful is cg_lagometer 1
The attack Script:
set attacking "vstr at1"
set at1 "+attack; set attacking vstr at2"
set at2 "-attack; set attacking vstr at1"
bind r "vstr attacking"
Press R for once constant attack and to turn it off just press R again.(Doesn't have to be R, you can change it to any key you want)
As far other interesting commands, I suggest, if you have the time and patience you look through the pages in this thread, you will find a lot of very interesting stuff.
