The text is copied to the new location in your current window. Make sure the window has input focus. In the other window, point to the text you want to move. Drag across the text you want to move. The text is highlighted as you drag across it.
Some applications use different methods for moving text.
See each application's documentation for an explanation of how to move text in that application. Deleting selected text this way is called pending delete . With pending delete, you can delete large blocks of text with one keystroke instead of pressing the .dK key repeatedly. To avoid pending delete after you select some text but before you press a key, point to the selected text and click MB1. This cancels the select.
