Placing Doors and Windows Independently from Level

We all know that, when in a plan view and starting a command, by pressing the Shift keyboard button we enable the Ortho constraint.

In a 3D view however, when placing a door or window, these elements will automatically be placed on the levels specified in your project (Where after one can specify the correct head/sill heights). When pressing the Shift button though, you will be able to place these doors and windows independently from your level.

Although this might not be a game changer, it is a nice to know.
