I really need a shortcut button for swapping between languages in google translate. Do you guys know anything about?
You can easily swap languages with shortcut Ctrl+Shift+S (or Cmd ⌘+Shift+S for MacOS users).
It looks to me that Google Translate doesn't have keyboard shortcuts, there isn't nothing on the UI and on the official help.
There are a couple of Chrome extensions that claims to add shortcuts to Google Translate but I didn't tried them.
