## Summary
Keyboard shortcuts such as Shift+S get triggered even when other keys
(Ctrl/Alt) are pressed, creating conflicts with browser or OS shortcuts.
This PR makes keyboard shortcuts more strict: the exact combination
needs to be pressed, no extra keys allowed.
--> Ctrl+Shift+S will no longer trigger the Shift+S shortcut to add a
sticky note
