Keyboard and Function Keys
If users are having problems activating operations from the keyboard, you check the following areas.
Clearrest Key
If you do not want the Return key to clear the data from the rest of a field, set the TERM_INGRES logical/environment variable to a terminal mapping file that does not use the clearrest key. This is usually a setting that ends in "i;" for example, "vt100i."
Windows: If you do not want the Enter key to clear the data from the rest of a field, rename the following files in %II_SYSTEM%\ingres\files by typing:
rename ibmpc.map ibmpcold.map
rename ibmpcalt.map ibmpc.map
FRSkey Settings
Users can accidentally select menu items by striking a function key that does not have an associated menu item. This is possible because FRS key settings do not override default menu item key assignments.
For example, Function Key 7 activates the seventh menu item even if that menu item has an FRS key assignment that is displayed with the menu item text.
