Thanks, David.
I used Gnu APL ]keyb command to verify. I see that del-underscore is in two places. My guess is that akt is only used with GNU APL. I propose that either GNU APL be changed to only have one key with del-underscore (and the corresponding ]keyb corrected), or akt be allowed the anomaly to remain in sync with GNU APL.
Additionally, if there is a change in GNU APL, all of the key binding I and others have supplied will have to be changed, and my custom made keyboard would have to be changed.
Although in a perfect world I think it best not to have the same character in two places, I think making akt remain in sync with GNU APL is best - either way.
Thanks.
