I got a couple of questions about my keyboard. I don't remember how my keyboard originally worked and looked. I'm wondering if I might of changed something inadvertently? We're the lower left 4 key blue and the lower right 2 keys blue? When I'm typing now there's a line underneath the word Im tying until I hit the space bar, don't remember that? When I tap the up arrow to changer from capital letters to lower case letter I have to double tap? Used to have something resembling a bubble on some wordstuff, don't see that any more? Thanks for response.
