AH = 45h: Window Keys & Cursor Tracking Control

This function enables or disables display window movements that may be caused by two different mechanisms. Window movement will occur only in zoomed text modes, regardless of whether or not the function is enabled. This function writes to the WINFLG variable in BIOS RAM that records the control state.

When cursor tracking is enabled, the window will be moved to maintain the cursor in the display.

When the window key movement is enabled, the MENU-ARROW and MENU-SHIFT-ARROW keys may be used to control placement of the window. On the HP palmtop, the MENU-ARROW keys repeat.
