You can assign two global keyboard shortcuts to common ScreenToss tasks.
Capture screen: By default, ScreenToss uploads any screen shot your take with the built-in system keyboard shortcut: ⇧⌘4 (Shift+Command+4). If you configure your own, custom shortcut, ScreenToss will no longer upload screen shots taken the traditional way.
This is an alternative to temporarily disabling ScreenToss when you don’t want to upload a screen shot.
Share file: Opens a file browser so that you select a file/image to upload and share.
Share clipboard: Uploads and shares the contents of the clipboard.
