@leocg said in Alt+T is opening tabs?..conflicting with browser app keyboard shortcut:

@sandcastl3s Did you check keyboard shortcuts section in settings page?

A thousand thanks. I'd never seen that part of settings and don't use tab islands - the shortcut was 'open new tab in island'.

I really appreciate your help, just tested my software and the keyboard shortcut acts as expected.

Mark as solved!
