i am using a dell laptop and i want to use the euro sign on the key numbered 5.how to use that and i am not having Alt Gr key on my keyboard
Hello and welcome to Tom's Hardware Forums.
If the € symbol is showing on the 5 key, there must be a key combination to use it. Using the Alt.Gr. key, the Euo symbol is on the 4 key along with the dollar which doesn't need Alt.Gr.
It still doesn't show up in my XP Character Map but if you have windows 7, it may be there - go from the Start orb to Accessories>System Tools>Character Map and look through the symbols.
Until you find the method, clipboard this one € and store it.
