Have just updated to 2026.2.1 from 2024 and have gone to make new user settings. I like to customise loads of buttons but the majority of the editable options are missing. Why aren’t they available to edit?
Set focus (track)
Previous / Next transitions
Mark in around selection
All these keyboard shortcuts should be available. Keep in mind that the Keyboard Shortcuts Editor is context sensitive, so, for example, you need to be in the Timeline environment to have shortcuts like Mark In/Out Around Selection available in the list.
If they still do not appear and you haven’t started your customization you could try to reset the keyboard shortcuts associated to your profile in the Setup Application (in the User tab).
You could also check that the shortcuts exists on disk by looking at the content of /opt/Autodesk/presets/2026.2.1/shortcuts/. For example the Mark In/Out Around Selection shortcut is listed in the shortcuts.local.json file.
