[Bkchem-user] Chemistry/info via shorcut - but how to quit the popup window via keyboard?

[Jan-Moritz Adam]

Hi !

With Ctrl o + i 
one gets the "Info on selected molecules" popup window.


But I am not able to get rid of this
popup window again via a keyboard shortcut.
I can change the focus with the tab-key,
between the info box and the ok button.
But when I have the ok button in focus
hitting "return" doesnt have no effect.

Is it possible in anyway? (alt + F4 is no option for me).
