How to delete a shortcut?

Hello,

I want to create this shortcut “Alt + L” but an already existing shortcut overrides it.

The shortcut that overrides it opens this drop-down list

and I can’t find it in the shortcuts.

I’m pretty sure this is a Windows Underline Access Key, not a Dorico shortcut.

I don’t have a Windows computer to hand but you might find this guide helpful for disabling Underline Access Keys: Enable or Disable Underline Access Key Shortcuts in Windows 10 - TechCult

If you wish to use them elsewhere (on the other Dorico menus, or in other applications), choose a different key combination for whichever Dorico function - to the best of my knowledge you can’t selectively disable Alt-L.

Thank you for your quick response.
