Shift + 7 yields &, which is known as an ampersand.
If its what i think its above the number 7 so you do shift 7 to get this sign &
I mean how can i put the letter a on the Keyboard.
Shift
shift+8 thats not it
[shift] + [F3]
2 they are shift+9 or shift+0
do this :( press shift + ; and press shift and 9
no
Shift+5
Hold down shift and push 2 on the number row. (Depending on the type of keyboard - mine is <shift> + <'> )
The shift-9 combination on a keyboard types a left parenthesis.
