+ * Switch the reference group of shortcuts on the HUD's hotbar.
+ *
+ * The hotbar contains eight slots for user shortcuts - medkits, implants, and text macros.
+ * Next to the first slot are up and down arrow buttons with a number.
+ * By progressing through the options available from the arrows, eight sets of eight shortcut slots are revealed.
+ * Which set is visible determines the effect of the activating the respective of eight binding keys for the hotbar.
+ * Each set is called a "bank."
+ *
+ * When shortcuts are manipulated, the bank acts as a reference point to the set and moves that set of eight shortcuts onto the HUD.
+ * Adding a shortcut to the first slot when viewing the second bank is the same as added a shortcut to the ninth slot when viewing the first bank.
+ * Obviously, there is no ninth slot.
+ * The slot value merely wraps back around into the next bank.
+ * The `bank` value can also wrap around through the first set, so requesting bank 8 (`80`) is the equivalent of requesting bank 1 (`00`).
+ * @param player_guid the player
+ * @param bank the shortcut bank (zero-indexed)
