If you start this application, but the text cursor into the first TextArea and press Ctrl+I, the text of the second textarea is set.

This is quite unexpected, as the shortcuts live within a contextmenu of their respective textareas.

I think the current situation of not supporting the same accelerator to execute different actions is suboptimal.
