Strg+Umsch+U - Captures text from an object under the mouse cursor. (An object is a window or a control, such as a button, selection box, menu etc.) After placing the cursor above the text you want, use the Hotkey combination (Strg+Umsch+U) to capture the text.
Example: Capture the text of an entire pull-down or pop-up menu.
To give yourself time to move the cursor where needed before the actual capture, set an additional delay for it in the TextSnap™ tab under Capture Settings.
