Keyboard shortcuts will make you more productive in HeavyBid. Here is a simple easy to remember shortcut for Tree View. In Version 2015 the feature was added where the “F6” key will cycle through the major fields. For example if I want to go from the resource screen at the bottom back to the Biditem Tree (or view) just press F6. And if you keep pressing F6 it will continue to cycle through the input fields.
