Delete item with keyboard

[jidar]

When attempting to delete an entry using only the keyboard, the desktop mac app does not put the cursor on the popup confirmation window. 

 

The window pops up, and TAB, ENTER, or the arrow keys do not function. The only key that appears to work from here is ESC, which does close the window. Because ESC works, but nothing else I can conclude that the window has focus and is accepting keyboard keys, however this is not the case for any _other_ key.
