Here, here!
I think you have received an answer to your question, however rudely...
For those of you who replied...it is clear that this person is new to the
computer or he/or she would not be asking this question. He/she may also may
not know that writing in lower case lettering is more acceptable when having
a conversation...So if you are considerate enough to answer his/her question,
the least you can do is answer it with some level of understanding and
consideration and kindness to someone who is just learning.
