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
