This is a 32 bit bitmap in which each bit set to 1 enables the corresponding function key to be sent to the control. For example, &h00000001 enables F1 to be sent to the control and &h00008000 enables F16 to be sent to the control. (The upper 16 bits correspond to Shifted F1 through F16.) The following table indicates how the control would normally interpret the function keys:

History

2006 August, A-Shell 4.9.963:  XTEXT.SBR now supports an option to make the Save icon on the toolbar act like "Save As" (i.e. display a dialog to allow you to choose a filename and location) rather than just "Save." To active this option, clear bit 3 (corresponding to the Save command, which is equivalent to F3) and set bit 19 (corresponding to the Save-As command, or Shift+F3). For example, if you previously had TXC.FMAPCTL = &H000000FF (i.e. send all the functions corresponding to F1-F8 to the control), you would change this to &h000400EF to force the Save button to act like Save-As. Note that this would not affect the keyboard commands F3 and Shift+F3, which would continue to distinguish between Save and Save-As.
