is a good thing. Use it.
I have a directory /home/<myusername>/Movies
which is the place I keep the screencasts I record.
So, open a Terminal, then
It starts recording as you can see from the flickering mouse pointer.
Record happily and when done come back to the terminal (simply Alt+Tab till you get the Terminal) and pres Ctrl+C
Then it will count up from 1% to 100%.
