All of my keyboard shortcuts have stopped working in the latest version of illustrator CC.
Can access the commands through the drop down menues, but not thorugh the keys.
Any ideas why this has suddenly happend and how to fix?
Did you just update?
When updating, did you reset the preferences?
You could try and reset the preferences. Unfortunate during the last updates it was needed in order to make Illustrator work.
The process will destroy all settings. You can rename the folder in order to try if it helps at all. Procress is described in here. https://helpx.adobe.com/illustrator/using/setting-preferences.html
If it doesn't help, name the folder back.
Thank you so much - resetting the Preferences has worked. All keyboard shortcuts are back.
