What key should be used to add items when selecting multiple elements like a wall?

The Tab key is used in various software applications, including BIM software, to cycle through selectable elements within a tool. When selecting multiple elements such as walls, the Tab key allows the user to efficiently navigate through different elements that are overlapping or closely situated. This is particularly useful in a graphical interface where objects may be stacked, facilitating a more streamlined selection process.

By pressing the Tab key, you can highlight each item in succession, giving you the ability to choose the specific elements you want to include with precision. Once the desired wall or element is highlighted, you can then execute your selection command (like clicking or pressing another key) to include it in your selected group. This method enhances productivity and accuracy when managing multiple elements in your design.
