When selecting any kind of object in 3D space, there may be situations where a closer object obscures a farther one, making it impossible to select the far object without either reorienting the camera or hiding the closer object. In all select modes where this issue can occur, you can use the [!keybind]Page Down, [!keybind]Page Up, [!keybind]Home, and [!keybind]End keys to selectively ignore closer geometry for hit detection, allowing occluded objects to be selected.

The mouseover item label in the lower right corner of the view shows the number of available objects that can be selected at the cursor position across all depths, as well as how many layers have been peeled back, after the ↓ symbol. The [!keybind]Page Down key will peel back one layer and allow the next object farther away to be selected. The [!keybind]Page Up key does the reverse. The [!keybind]Home key resets all peeling and returns to selecting the frontmost object. The [!keybind]End key skips to the farthest-away object in depth order.

In some situations, you may see something like "↓1/2" while nothing is currently highlighted by mouseover. This occurs when there is an object that can be selected, but it is occluded by something that would not be selectable in the current mode. This works the same as the above case, with an extra "no selection" layer at the top of the peel stack. [!keybind]Page Down or [!keybind]End will allow the object(s) underneath the occluding object to be selected.
