Is there a way in the program to tell if a user pressed a tab or a shift tab.

We need to do different things depending on which one pressed.

We looked at the data item EVENT-CONTROL-ID but it doesn't seem to tell us anything.

What we are trying to do is on a transaction entry screen when the user gets to the amount field, which is the last field in the line, we have an after procedure routine setup to process the line and update the record.

We test for enter key and update if enter pressed but we also need to update if tab is pressed. Currently it goes to the next item in tab order.

Any suggestions would be greatly appreciated.

    Try set environment "keystroke" to "exception=69 kB" and then you can trap the exception value when shift tab is used.

    This will work on Windows but may not work in Unix as it turns out that a UNIX keyboard doesn't send a different escape sequence when the user presses TAB or SHIFT-TAB, so there is nothing that the runtime can do to detect the difference.

    Just wanted to see if anyone had any new thoughts or found anything new on handling this. We run a unix character screen for all of our GUI screens and are looking for a good way to handle shift-tab... ...especially in drop lists. Right now the best we have found is an option to "go to 'field'" listed as a selection in the drop list.

    Thanks for any other input or thoughts. Mike

    Just an fyi, we found that making a modificatio to the termcap file fixed our problems in Unix. We had to make the change for ever terminal type we used and now shift-tab works the same in unix as it does in windows.
