Need to be able to Tab into a combo box using the code I already have

I found a great way to automatically fill in a value by starting to type it, but to get into the combo box I have to double click the cell with a drop down list, what I would like to do is to Tab into the cell(combo Box) as well as double click, I already have a way to tab out of the combo box, and that works great, I just don't know how to get into the combo box, I am including a copy of the file. "Que", "Type", and "Completion Status" all have a drop down list, I need to be able to tab into "Que" then "Type" then "Completion Status", enter the beginning of the value I want, which should autofill, then tab to the next one, any help would be appreciated, thanks

the code I have used comes from: http://www.contextures.com/xlDataVal11.html

what I'm looking for is thus:

in a normal spreadsheet, you can Tab from cell to cell, and even if you have a combo box on top of a cell it will only tab into the cell and not the combo box

with the code I have found online and am using, the option to double click a cell: have a drop down list appear, start entering a value, and it auto-completes, is present. Then I can tab out of that combo box and it tabs to the next cell, which I then have to double click that cell to then repeat the process

what I want to be able to do is have the Tab do the same thing, without having to double click, but keeping the double click option as well

thanks

yes, I replaced the code I had with the one you gave, and It did work, thank you
