Currently after the user clicks on a checkbox (including switch button) or a dropdown menu, the widget grabs the keyboard focus:
This means keyboard commands like the arrow keys or the Space key will trigger both Hookpad’s own actions (change note / chord degree, play) and the default actions on those widgets (select previous / next item, toggle button). This is very inconvenient when using the keyboard to edit projects.
The editor should remove the focus on these elements as soon as they are selected; alternatively, the default keyboard actions on them should be disabled. This mainly affects the chord properties menu, but some other places like the key change menu also use them.
