Keyboard shortcuts in Mate

Mac app

Action	Shortcut
Open Mate from anywhere	Option+Shift+T
Translate	Return
New line in the input	Shift+Return
Swap languages	Control+S
Copy the translation	Control+C
Close the window	Esc

Change the global shortcut in Settings › Shortcuts › Open Mate. Click the recorder, press your combination, done. Clear shortcut removes it.

If you'd rather translate with Shift+Return and insert a new line with Return, use the swap control under Shortcuts in the pop-up.

Turn on Auto-translate clipboard in Settings › General to have Mate translate whatever you last copied when you open it with the shortcut. Copy, press Option+Shift+T, read.

Browser extension

Action	Shortcut
Translate selected text on the page	Shift+T
Swap languages in the popup	Cmd+Shift+S on Mac, Ctrl+Shift+S on Windows
Translate in the popup	Return (or Cmd/Ctrl+Return, see below)

Shift+T can be changed in Settings › On-page. With Mate Pro you can add more combinations, each translating into a different language, up to 21 in total.

In Settings › Prefs, Shortcuts in the pop-up lets you swap which key translates and which inserts a new line.

Browsers also let you assign a shortcut to open the Mate popup itself: in Chrome, chrome://extensions/shortcuts; in Firefox, the gear menu on the Add-ons page › Manage Extension Shortcuts.

iPhone and iPad

There are no keyboard shortcuts, but two quick actions save taps: press and hold the Mate icon on the Home Screen and choose Paste and Translate or Start Speaking.
