Hi Philippe,

> yes, I admit, I'm the culprit.

No problem about this!!!
And since I answer you, I would like to use this opportunity to congratulate and thank you for the gorgeous (you did it again!) last big update you made on ImageJ (i.e. the one on the tables).

I would have no problems with having to use a key modifier together with the delete key within my plugin.
Actually I had already tried this option before sending my first E-mail, but the "clear" feature of the delete key is still working even if an InputEvent value has been set for my code (unless I'm missing something in my code).

My best regards,

Philippe

Hi Philippe,

yes, I admit, I'm the culprit. The reason was that many other programs I
am used to require the "delete forward" key to delete things (except on
Macintosh), e.g. deleting items from a list. ImageJ was kind of an
exception, so I often ended up using the wrong key, and I was wondering
why it did not delete.

But maybe I am the only one? What do the others think?


Philippe: Would it be acceptable to have some modifier key (SHIFT, ALT,
CTRL) for the special 'delete' function of your plugin?
I think it would not be a problem to restrict the ImageJ keyboard
shortcut to the delete key being pressed without such modifier.
(currently it does not check for modifiers).


Michael
