Cursor Movement to a combo box
 

I have developed a spreadsheet with combo box drop downs. When the sheet is
protected it will TAB to each cell that I require an answer be typed, but it
will not TAB to each combo box so that you can select an answer. Could
someone please advise whether you can include combo boxes within the TAb
order? Also is there a way that when you select the combo box that you can
type the first couple of letters and the answer automatically comes up?
