Hello. I have an HTC

Question

Hello. I have an HTC Touch Dual with full qwerty keyboard slide out. I have two questions.1. I cannot find what is Button two in descriotion. I want to assign that button to voice tagged calls so I can press button two and make call by speaking the voice tag.2.Secondly I have an icon that reads 12# and manifests tow ways. First it is there when I open it and it disaapears when I key the numbers to unlock. I cannot find the icon anywhere. Secondly sometimes and it seems to be after I have fully turned off the phone charged it up and then switched it on. There is a message on the bottom left which says notification but when I press that, all that comes up is a little blank screen and the only option is to hide it. If I leave the phone onit eventualy goes away and the word calendar appears which is the normal instruction in that bottom left of the phone. Can you assist as to how to avoid that and what is the icon and how does one set it up for whatever purpose it serves. Thank you,Tony [e-mail]
