It doesn’t have a keyboard shortcut by default, but you can bind 'Move Window to the Left Side of the Screen' and 'Move Window to the Right Side of the Screen' in Keyboard > Shortcuts > App Shortcuts.
another thing to note is that you can add shortcuts to any application as long as it has a menu title... you just have to type the menu item exactly. this also works to effectively remove shortcuts from apps that hijack something that you use elsewhere and don't want available ever. you have to set it to something like control option command shift F15 or something that you'd never use.
