At first you have to exuse my English, i know it sucks, but i hope some one can understand my questions!!! (im from Sweden

Im a totaly new to this program, and i hope some one can spare some time to help me with a couple of questions!!
First is the announdements, i did read the "readme file" and find out that i could do a script for announcements and pictures so i just have to type a number to view it, it says "Then you can type the number and press the tab key to display the announcement"
Where i'm i suposed to type this number?! in the console or where?! tryed every where and nothing happend!? and i have created a script as the exemle file!!
Then i also wounder if there is a simple way to adress keys to overlays, instead of useing the web remote and use the mouse!!
Tried use the R4 options/settings/keys/assign keys, but when i chose letter to adress to i don't know how to chose overlay!!!
It's probebly simpler to write a text file or something...
And how do you know when "numpad/Tab Scripts" is enabled? when i chose it it doesn't change to "disable numpad/tab scripts" or show on or off
in some way...
I don't know but that could be the problem for me why i can't get the script working!!
This is probebly totaly stuped questions that have there answers in some readme file, but as i said my english is terrible, so i have probebly missed it.
I would be wery glad i some one could take there time to help me

Thanks
