The Shift key is not detected when defining some shortcuts

• Jul 16, 2021 - 12:50

I am trying to define a shortcut that uses Shift + Up as a hotkey, but the Shift key is not detected when I press it in the "Enter Shortcut Sequence" menu. It is strange that for some other hotkeys this key is detected (e.g. Shift + A, Shift + B, Shift + C...).

I found this Musescore page reporting the problem. However, it is dated December 2014:

https://musescore.org/en/node/41551

Is there currently, as of 2021, any solution available to fix this problem?

#41551: Shortcuts using shift are not registered correctly. is closed since 6 years, and most probably enttirely unrelated

Seems than indeed Shift is not available as a modifier for the arrow keys

Actually the fix for the above mentioned issue might be the cause for this.

Funny enough: Shift+up/Down/Left/Right are all used in the existing shortcut already.

Looks like a bug to me, please report in the issue tracker

Indeed, this

      // remove shift-modifier for keys that don't need it: letters and special keys
      if ((k & Qt::ShiftModifier) && ((e->key() < 0x41) || (e->key() > 0x5a) || (e->key() >= 0x01000000))) {
            qDebug() << k;
            k -= Qt::ShiftModifier;
            qDebug() << k;
            }

esp. that || (e->key() >= 0x01000000) excludes arrow keys here, the Up key sends 0x1000013

actually it is already the || (e->key() > 0x5a), the condition after that can never get reached, is utter nonsense

Thanks, how should this code be used?

No idea how to correct the code there. It pretty clearly is a bug though

Very strange that it went unnoticed ever since MuseScore 2.0

Edit: it did not, see #219191: can't create non-alphanumeric keyboard shortcuts using "shift" key
