Mouse Menu Key Sequences: Corrections and Additions

ID: Q67854

The information in this article applies to:

Microsoft Mouse driver for MS-DOS, versions 6.x, 7.x, 8.x, 9.0

SUMMARY

Page 71 of the "Microsoft Mouse Programmer's Reference" lists "Key Sequences That Can't Be Simulated" using the menu programming TYPE statement. These keys cannot be simulated in a mouse menu because the key or key sequence is suppressed in the ROM BIOS. The list that is presented in the guide is incomplete, and in certain instances it is in need of revision.

MORE INFORMATION

Each suppressed key mentioned is the lowercase character on the key. It is understood, but not explicitly stated, that the uppercase character on these keys will also be suppressed. A number of keys and key combinations that are suppressed and cannot be emulated are not mentioned in the guide. Some of the additions and corrections that can be made to the published list are given below.
