Status Icons What are these?

[Guest bigwol]

I've got a ZTE Blade with Android 2.3.5

a set of three Status icons appeared recently on the top bar and I don't know what they are

Any ideas??

Found it! - They are statusbar softkeys, which allow Home, Menu and Back to be used by pressing the softkey on the notification bar - I must have enabled it while messing about in the Settings. I changed it back so the option is unchecked, rebooted, and I've got my notification area back!!
