why do i have little embossed lines underneath the letters ‘f’ and ‘j’ and underneath the number ‘5’ on my number pad, or am i the only one?
Mine does, too. It’s to let you know you’re on the home keys when touch typing. Your index fingers go on “f” and “j” and your middle finger on “5” when using the numeric pad.
aahhhhhhhhhhhh ok that makes sense. thank you. quick reply too! 
Hey! that’s cool, I alway thought it was to give your index fingers something to do while you were thinking. 
Now, can someone tell me what the SysReq key is for?
