Resolves: musescore#25824 When using Russian keyboard layout, and when there is a `Z` shortcut and a `Ctrl+Z` shortcut, and you press `Ctrl+Z`, we add four shortcuts: - `Z` and `Я` - `Ctrl+Z` and `Ctrl+Я` When pressing `Ctrl+Z`, Qt thinks there are two possible keys: ``` 17:42:43.971 | DEBUG | main_thread | Qt | - QKeyCombination(ControlModifier, Key(1071)) / QKeySequence("Ctrl+Я") / ⌘Я 17:42:43.971 | DEBUG | main_thread | Qt | - QKeyCombination(NoModifier, Key_Z) / QKeySequence("Z") / Z ``` (output seen after `QLoggingCategory::setFilterRules("qt.gui.shortcutmap.debug=true\nqt.qpa.keymapper.debug=true\nqt.qpa.keymapper.keys.debug=true");`) The latter, `Z` with no modifier, makes no sense to me, but whatever; Qt thinks it must be. As a result, Qt thinks the shortcuts are ambiguous: it doesn't know whether to activate `Z` or `Ctrl+Я`. The solution is to avoid adding `Z` as a shortcut; it won't be necessary anyway, as `Я` suffices. Same story goes for other single-letter shortcuts.

When using Russian keyboard layout, and there is a
Zshortcut and aCtrl+Zshortcut, we add four shortcuts:ZandЯCtrl+ZandCtrl+ЯWhen pressing
Ctrl+Z, Qt thinks there are two possible keys:(output seen after
QLoggingCategory::setFilterRules("qt.gui.shortcutmap.debug=true\nqt.qpa.keymapper.debug=true\nqt.qpa.keymapper.keys.debug=true");)The latter,
Zwith no modifier, makes no sense to me, but whatever; Qt thinks it must be.As a result, Qt thinks the shortcuts are ambiguous: it doesn't know whether to activate
ZorCtrl+Я.The solution is to avoid adding
Zas a shortcut; it won't be necessary anyway, asЯsuffices.Same story goes for other single-letter shortcuts.
Should be tested very carefully, also with other keyboard layouts than Russian (for example, what effect will it have for AZERTY users...)
