What is the four cake slices Y/-Y/X/-X/House in Device tab?

This might be a really stupid question from a total noob but what are the four cake slices Y/-Y/X/-X/House in Bambu Studio’s Device tab? (Far right/up corner of the Device tab)

Manual travel of print head on X and Y axis in 1 and 10mm increments. And middle icon returns home.

It is a very poor rendition of the control panel on the P1P.
It sort of looks like the hard buttons, but it does not work the same way.
