It is not that the users rely only on keyboard, they also have a mouse. I can't narrow down the number of fields in this case. There are also fields that edit a table, such as Male, Female, Unknown. This will almost never need to be editted. But these must be present on the form. If you have all fields tabindexed, it becomes 26 [Tab]-key clicks.
The user where the application is targeted at is not a consumer, but an employee. They have to be able to have fast input times for their most regular input patterns. So I thought if reducing the number of fields is not an option, than excluding seldom used fields fomr the tab focus is.

True, but that is a problem that could be fixed easily with visual aids.

The application already doesn't take care of Non-sighted users. They aren't included in our target group.
Has anyone have experience with the same kind of situation?
