While fiddling with settings on the latest Beta version (220.127.116.11 / beta 273516) on Windows 64 bit, I found what could be a bug to resolve. After swapping the default keyboard shortcuts for the “Paste” and “Paste and Match Style” (I prefer to have Ctrl + V for Paste and Match Style and Ctrl + Shift + V for the straightforward Paste), the new Paste and Match Style shortcut (set to Ctrl + Shift + V) doesn’t match the default style I set for the Notes panel (I changed the style for that, too). I haven’t tested whether it is influenced by the change of the Notes panel style that I set or not (I’m not willing to reset all to default at this stage), but it may be.
Once I reset the keyboard shortcuts to default, though, they work as expected in the Notes panel.
I tested changing just the Paste shortcut (to Ctrl +Alt + V), without changing the default one for Paste and Match Style, and the new shortcut for Paste doesn’t work for the Notes panel at all, even after restarting the program. Ctrl + V and Ctrl + Shift + V work, though.
I tested changing both (Paste to Ctrl +Alt + V and Paste and Match Style to Ctrl + V), and on Ctrl + V, the app closes for some documents and works as Paste rather than Paste and Match Style for others. Ctrl + Alt + V simply inserts a capital V rather than clipboard text.
