Keyboard interaction issues with dynamics popup

[avvvvve]

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

Follow-up from #26189. There are 3 parts to this issue:

---

1. Shift interaction

Original comment

One problem though is that the shift-to-move-beat-position interaction only seems to work if you select the dynamic with the mouse. It doesn't work if you select the dynamic via keyboard navigation or after having just inputted it via either the popup or the input text field.

Also doesn't work if you add the dynamic from the palette:

2. Alt + Left/Right arrow interaction

Original comment

When you click on a dynamic to select it, Alt/Option + Left/Right arrow will no longer move the selection to the next/previous element. Instead, it nudges it to the left/right as if just an arrow with no modifier was pressed.

• The same happens even if you get the popup to disappear by some means and then try to Alt + Arrow, i.e....
  • Scrolling the score to close the popup
  • Move focus to the popup with the keyboard, change the dynamic, press esc to close the popup leaving the dynamic selected (shown in the video at 0:11)

3. Shortcuts should still work while focus is in popup

Original comment

When you tab to move focus into the popup, some shortcuts work (i.e. voice assignment) but others do nothing. These shortcuts should be possible without having to press esc first:

• Alt + Left/Right arrows to select previous/next element (popup should close)
• Alt + Up/Down arrows to select other elements at that beat position (popup should close)
• Ctrl + C to copy (popup should remain open)
• Ctrl + X to cut (popup should close)
